Roto Grip TNT Infused Bowling Ball

(26 reviews) Write a Review


Just like the original, this version is also engineered to blow up racks and take names.

Featuring the same Torpex Core with TORQUE SPHERE Technologywe knew the sole focus of this project was formulating the ideal coverstock to not only compliment the TNT, but also compliment the entire Roto Grip product line.

Explosive Performance PLUS SOME was our goal, and well, lets just say we CRUSHED IT!

Starting with our eTrax PLUS coverstock material, we went to work mixing up and mixing down both the pearl and solid materials. After months of rigorous testing and analysis we were able to formulate the response to friction we were looking for thanks to this 2-part pearl / 1- part solid concoction.

Now go ahead and say that again with us out loud, length and forgiveness. That was the philosophy we used in creating the latest installment of the TNT Series of balls – TNT Infused. Just like the original TNT before it, we use the term “benchmark” to describe our latest masterpiece of destruction. Armed with the same Torpex Core, we opted this go around to wrap that explosive core with our newly formulated pin-piercing shell – eTrax PLUS Hybrid. This version is the synergistic blend of 2-parts pearl / 1-part solid. So, if you are in the market for an explosive energy release through the pin deck, then you my friend have come to the right place. Release Date: November 3rd, 2023 The Roto Grip TNT Infused comes Reacta Gloss polished, but I changed the cove to 4000 Abralon (no polished), and what a delightful surprise it was. Benchmark, Responsive and Explosive. Fits between my TNT and 900G Xponent From the moment I sent this ball down the lane, the explosive nature of the Roto Grip TNT Infused was evident. The energy transfer from the core to the coverstock is nothing short of impressive. The dynamic design of the weight block allows for a powerful release, creating a visually striking explosion of pins upon impact. Whether you're a power player or someone looking to increase their pin action, the TNT Infused delivers that explosive performance that can make a real difference in your game. One of the standout features of the Roto Grip TNT Infused is its remarkable responsiveness. The ball reads the lane with precision, reacting to the oil patterns with a level of control that is truly remarkable. This responsiveness allows for adaptability on various lane conditions, making it a versatile choice for both league and competitive bowlers looking for a complementary ball to the TNT. The TNT Infused responds with consistency, providing a level of control that gives me confidence in every shot.

    Roto Grip TNT Infused Cover: eTrax™ PLUS Hybrid Reactive Weight Block: Torpex™ Core (Symmetrical) Color: Glow Orange/Copper/Plum Review: Looking for a versatile benchmark ball that will be great as the first ball out of your bag on league night? Looking for a upgrade from that Tropical? Look no further than the TNT Infused. This ball plays off the original success from the TNT. The TNT infused is the type of ball that will get down the lane while offering plenty of pop on the backend. Being that the ball is a hybrid you won’t have to worry about the ball reading to early on the lane or over hooking on you. Being that the ball comes with the reacta shine you will not have to worry about getting through the fronts, it will get cleanly through the fronts while offering a good pop when it hits the pocket. When comparing this ball to other’s in my bag I am often drawn to the OG Hyroad with the TNT getting the slight edge due to bright vibrant colors. I would highly recommend this ball to anyone who is looking for a new hybrid in their bag. Will Tefft Roto Grip Pro Shop Staff Member #SquadRG

    The TNT Infused is our new Hybrid from the TNT Line. With the Torpex Core and eTrax Hybrid Cover, it really digs into the lane like the original TNT. Comparing it to my Zen and weaker asymmetrics, this ball still out curves then all. Never struggles to get back from whatever angle you can think. This ball is a monster!

    Hey everyone, I'm back with another ball review, and this time it's for the Roto Grip TNT Infused. In 14 pounds this ball is wrapped in an eTrax Plus Hybrid Cover and comes with a reacta gloss finish with the Torpex symmetric Core from the original TNT and has an RG of 2.54, Diff of .051. The layout for this ball is 5.5 X 4.5 X 1 and I went on the weaker side to have a ball that hooks but to be used when they get drier. There are many videos online showing this ball as a hook monster but not knowing things like their layout or what the pattern hurts the person watching as sometimes it is hard to understand what you are watching. I hope this helps and please let me know on the socials. I filmed this ball after league to show what it looks like on a drier shot as when I did throw it on fresh for me it didn't look great and yes that is part of the layout. This ball comes with the reacta gloss finish and like the 4Kfast I didn’t find that surface to be to my liking and the same goes with this ball. Before holes were put in I hit the ball with a used 2000 pad just to knock off the shine. This ball will stay in the bag for some time to come and will put in work later in events or even on a shorter pattern.

    The all new TNT Infused is Roto Grips newest addition to the HP3 line. The infused features the Torpex Core (in the original TNT as well) with the eTrax Hybrid coverstock (with Reacta gloss) wrapped around it. I think that the Infused was a great addition to the line, I felt that the original TNT was a ball that was very shot dependent. If I needed a ball to be slow and rolly it was my go-to ball, however, I thought that the coverstock may have been too strong unless there was a lot of oil in the front part of the lane. I think that the eTrax Hybrid coverstock is more of what I like to see out of a ball, it allows the ball to slow down in the midlane without bogging down when it gets to the pins. The TNT Infused is great when you want to move in and open up the lane without sacrificing midlane control. This ball made a good ball (TNT) even better!

    Roto Grip TNT Infused Layout: 4.5 x 5 x 2 Storm Pin Buffer Layout Rev Rate: 325 rpm, 7 degree of axis tilt, 40 degree of axis rotation Testing information: 41 foot THS (medium to light volume) Bowling Center: Fulton Bowling Center Kegel Machine – Brunswick Anvilane The Roto Grip TNT Infused utilizes the eTrax hybrid coverstock and the Torpex weight block. I have seen some reviewers opine that the ball reaction of the TNT Infused is Marvel Pearl like. Those are big shoes to feel as the Marvel Pearl was one of my all-time favorites. However, the TNT Infused is very similar. It is clean upfront and nice backend motion once it touches the dry boards. The TNT Infused is very different than the original TNT, which was smooth and controllable. The TNT Infused is in that Storm Virtual Energy Blackout space, but as a symmetrical option. The TNT Infused was not quite as long s the VEBO for me, but similar backend motion. I will used it as my No. 2-3 ball after my Magic Gem or Eternity PI starts to hook too soon and won’t carry that stubborn 10-pin. Visit your local Storm VIP Pro Shop! #Stormnation #SquadRG

  • TNT Infused Review by Luke Rosdahl

    Posted by Luke Rosdahl on Nov 24th 2023

    The TNT Infused is a new symmetric ball in Roto Grip’s HP3 line. It features the eTrax plus hybrid cover, which is a clean and responsive cover that we’ve seen before on the RST X-2 in pearl form, and on the TNT as a solid. The core is the relatively new Torpex core which comes in at a low 2.47 RG and a .052 differential in 15 pounds. The Infused feels like a longer and sharper version of the TNT, but it’s remarkable how much that improves the quality of the ball reaction. I’ve used the Infused on several different conditions with a couple different surfaces. The factory gloss is too inconsistent and sensitive for me, so I resurfaced it down to 1000 on a resurfacing machine, then finished it lightly with Storm’s Step 2 compound. The result was a strong rolling, but clean, firm, and slightly forward arc. The TNT was known for being surprisingly early and strong despite the cleaner cover formula, and unfortunately the front to back shape was too front heavy which made it lazy and apathetic down lane. The Infused adjusts that shape, giving it a lot more balance and resulting in a perfect balance of core and cover. The heavy rolling and early core gives a lot of stability to the reaction shape, while the cleaner and sharper cover gets the ball further down the lane and adds punch. This makes the Infused a surprisingly effective and versatile ball that reminds me a lot of the original Zen, just cleaner and sharper. Like the TNT, the reaction shape wants to be slightly forward, but the cleaner cover allows the bowler to control the shape a little better because you can get around it more without it digging in so early or being flat like the TNT was. It fits well for a variety of bowler styles on most league conditions, and will be a great option for getting into transition on more difficult patterns.

    Ben Lapointe 5.25 x 4 x 3 1 1/4'' up and 4 7/8 over The TNT Infused is Roto Grips newest piece in the HP3 line. This ball provides excellent mid lane read with its big core found in the original TNT as well. The pearl cover on this piece makes it sharp enough on the back end to get through the pins with ease, but does not want to go through with too much angle and 9 pin. I find this ball blends out wet/dry or over under really well. I find this ball very useful on sport due to its slower ball motion, making it more useful on low volume fresh sport patterns. Bowl up a Storm!!

I liked the TNT quite a bit when it came out but it does get slow at times. The Infused comes off the spot HARD. It is a lot of ball. Where the TNT gets off the spot slow and continuous and lets you stay closer to the friction, the Infused just goes. I HAVE to open the lane up to keep this ball online, but the solid part of the cover insures that it reads the front part of the lane, so oil is not a problem. Being a high performance hybrid allows this ball to be used on all sorts of oil volumes and patterns because it tries to get through the fronts more than a solid but it also jerks, but not as much as a pearl! Love some high performance hybrids!

  • TNT Infused - You have been WARNED!

    Roto Grip TNT Infused LAYOUT: 45 x 5 x 40 COLOR: Glow Orange / Copper / Plum CORE: TorpexTM Core COVER: eTraxTM PLUS Hybrid Reactive BOX FINISH: Reacta GlossTM BUILT FOR: Medium Oil FLARE POTENTIAL: High Consider yourself WARNED! Being a HUGE fan of Roto Grip hybrids: like my current main go to ball, Roto Grip Hyped Hybrid, I was stoked when I saw the TNT line was adding a hybrid to the line up first, before a pearl version was released. Being two parts pearl and one part solid, made me even more excited. The TNT Infused has the look of a past Roto Grip ball, the DareDevil Danger, which is still one of my all-time favorite ball lines, the TNT Infused rolls and reacts a little earlier and hits harder than my Hyped Hybrid. The multi-density Torpex core is responsive and when the Infused hits the pins, it is very explosive. Comparing to the Hyped Hybrid, on Pro-Lane and SPL, the Infused does change motions early and stronger than the Hyped, where sometimes the Hyped takes longer to respond, and I can move my feet deeper into the center of the lane and not have to play so straight on those 2 types of lane surfaces, don't get me wrong, I love playing straighter when I can, but when the Hyped does not quite "get there" a nice stronger step up is the Infused. It is now my benchmark ball on Thursday nights at ABC North Lanes in Harrisburg. So, now my league bags have the Magic Gem, TNT Infused, Tour Dynam-X, Virtual Energy Blackout and Hustle RIP. I would say that would be a well rounded arsenal. ( Saving the one spot for the IQ Tour U/78. I hope this provides you some good insight and information on how the Roto Grip TNT Infused works for me.

And the longer I rolled this new Roto Grip howitzer and watched its explosive results, the more the TNT Infused left me smiling from ear to ear! The TNT Infused combines the Torpex Symmetric Core and the eTrax Plus Hybrid Reactive Coverstock. And this winning duo of core/cover produced some fantastic results. So, let’s take a closer look at what’s behind the success of the TNT Infused. The Torpex Core is a well-crafted symmetrical core that produces a smooth and predictable motion any down-and -in player like me can depend on. I liked the vibrant torque that the Torpex Core had off my hand, and even with my low rev rate, the Torpex Core built a strong and continuous momentum as it rolled through the mid-lane. Unlike other symmetrical cores that roll out or lose their gusto as they hit the pocket, the Torpex Core turns that stored energy into a powerful pin-crushing machine. I found the TNT Infused has a relentless continuation and takes no prisoners as it plows its way through the pin deck. So, if you’re a straighter low-rev player like me, the Torpex Core will deliver results you can count on and a motion you can trust. Now, what elevates the TNT Infused above the competition is the eTrax plus Hybrid Coverstock! This two-part pearl and one-part solid mixture is “money” for any straighter player like me. And suppose you’re a league player who bowls in different conditions. In that case, you can count on the eTrax Plus Hybrid Coverstock to deliver consistency and an almost benchmark motion in nearly any type of THS condition. Whether on fresh or worn conditions, the eTrax Plus Hybrid easily clears the front part of the lane and has a predictable, smooth traction in the mid-lane. Further, as the TNT Infused makes its turn off the pattern, the eTrax Plus Hybrid has a crisp, responsive motion without being overly aggressive. So, if you miss right, the eTrax Plus Hybrid brings you back without being erratic. If you pull it left into the oil, the eTrax Plus Hybrid holds the line and has a smooth roll to the pocket as it finds friction. So, this type of blending and consistency makes the TNT Infused an excellent choice for nearly any THS shot condition you may encounter during competition. In conclusion, the TNT Infused by Roto Grip is a fantastic new release! The TNT Infused will have a place in nearly any league bowler’s arsenal. And if you are a straighter, low-rev player like me, you can count on the TNT Infused to keep your game in play all night long with scoring results that will keep you smiling until next week! So, stop into your local Storm VIP Pro Shop today and have your TNT Infused ready to blast the competition! The TNT Infused is well worth it!

    Roto Grip TNT Infused Coverstock: eTrax Plus Hybrid Reactive Box Finish: Reacta Gloss Core: Torpex Core RG: 2.47, Diff: 0.052 (15 lbs) VLS Layout: 5 x 4 x 2-1/2 Dual Angle Layout: 60 x 5 x 35 PAP: 5 3/16” right x 5/8” up Rev rate: 400 rpm Average speed: 16.5 mph Location: Prairie Lanes, Sun Prairie, WI Pattern: Medium volume THS The TNT Infused is the newest ball in the Roto Grip HP3 line. The Infused features the same low RG symmetrical Torpex core as the original TNT, but this time it’s wrapped in the 2-parts pearl and 1-part solid eTrax Plus Hybrid cover. The solid version of this reactive cover was on the TNT, and the pearl version was on the RST-X2. All that said, this new TNT Infused is designed to provide a bit more length and backend responsiveness compared to the original TNT. After just a few shots with the Infused with the out-of-box polished finish, it’s safe to say that it and original TNT are very different balls thanks to the differences in coverstock. The strong core still helps the Infused get into an earlier midlane roll, but the polished hybrid cover makes it much cleaner in the front part of the lane and helps to create a responsive backend reaction that’s explosive through the pins. Even though the out-of-box Reacta Gloss finish helps to create length and responsiveness, sometimes I find it also creates over/under reaction. As I often do with factory-polished balls, I lightly scuffed the surface with an older 2000-grit Abralon pad by hand to knock some of the factory shine off. Doing this helped on misses in the oil as the ball had a little bit more traction the dig out the 10-pin, and misses that got to the dry too early didn’t jerk as hard off the friction. By comparison, the original TNT reads the lane much earlier and is significantly smoother downlane, and the DUO is perhaps just a touch stronger than the Infused (due to the really strong MicroTrax pearl cover) but has a smoother motion off the friction. The TNT Infused is going to be a great ball for most everyone. It you want the earlier rolling benchmark-type reaction that the original TNT provided, but also want a more responsive downlane reaction, the TNT Infused is a no-doubter. For tournament players, this will be a great transition ball to go to after the Gem or Magic Gem. For league bowlers, I think the Infused is versatile ball that can be used all night, especially if you take just a little bit of factory shine off the cover.

The original TNT is the ultimate control ball. The TNT has the solid eTrax coverstock and is designed to provide a benchmark reaction. The Infused is built for length and forgiveness (think shiny benchmark reaction) with the addition of the eTrax PLUS hybrid (2-parts pearl, 1-part solid). The Infused provides a completely different reaction type than my similarly drilled TNT. The Infused is cleaner with a nice arcing motion on the backend. Compared to the another shiny HP3 line ball, the Duo, the Infused is easily 5 more in overall hook and continued more on the backend.

    Roto Grip TNT Infused Cover: eTrax™ PLUS Hybrid Reactive Weight Block: Torpex™ Core (Symmetrical) Color: Glow Orange/Copper/Plum Review: This is a great release from Roto Grip. The initial TNT technical data has benchmark ball written all over it, and now you have your benchmark hybrid. We drilled this ball with our normal layout: tweener, 350-375 revs, 16.5mph, layout of choice is 4x4x2 (pin is above bridge). With the out of box finish this ball took a couple of games to wear the cover down to a point where we felt there was a bit more hold or miss room. It seemed a bit picky the first 2/3 of the lane if you weren’t perfect, and our house shot isn’t too difficult. Although it did burn in a little bit after some cover wear we took a 2k abralon pad and on the fresh saw a much more predictable and consistent reaction that you would except out of box from a benchmark like the OG Hyroad, Xponent, etc. Overall this is a great piece for someone starting out with the first high performance piece or someone adding that benchmark Hybrid to their bag.

The ball features the same Torpex core featured in the original TNT but this time is wrapped in the 2 part pearl 1 part solid E-trax hybrid cover. The pearl additive and polished finish make the motion of this ball a suprising polar opposite of its predecessor. I tested this ball on our very high ratio house pattern. The longer 12:1 design of our house shot is very cliffed and as a result really locks you into balls which can stand up quickly to avoid the downlane OOB. The TNT infused has been great for this purpose as the fast revving core and quick response cover really get it make a quick change of direction. This ball is a little condition specific as the quick response can make it lock up and get forward a little too quickly for some. The reaction for me has been great for getting the ball to roll off the spot very violently. On a more blended condition I think the TNT Infused will favor bowlers with more ball speed.

    Roto Grip’s newest HP3 line ball is a 2 part pearl 1 part solid eTrax+ hybrid cover that is wrapped around the Torpex core. I drilled mine 5 x 5 x 4.5 and after throwing this ball for awhile, I believe this is going to be a HUGE hit. It was pretty clean through the fronts but it still handles the oil pretty well and the motion it makes on the backend with the ways it goes through the pins is what really sets it apart. This is going to be very versatile on where you can use it and the different motions it makes. You can add surface to make it better for the fresh or leave it shinny and have it own the transition.

  • TNT Infused a Nice Upgrade!

    Roto Grip TNT Infused Coverstock: eTrax + Hybrid Reactive Cover Finish: Reacta Gloss Core: TORPEX (14pd.) RG: 2.54 Differential: 0.051 Layout: 5 x 4 x 4 - 2LS Layout Extras: 2 3/4 Finger Depth, "X" - 4 1/2 D and 1 Inch Left Tester: PAP 6 1/2 R, 1 1/4 D Review: The TNT Infused features the eTrax + Hybrid Reactive which makes the TNT Infused a 2.0 version to the original TNT in the Roto Grip line of bowling balls. In comparison to the TNT the Infused is longer and more responsive and will be more angular than the original. Anything you desire in a ball to create a touch of length and control the TNT Infused may be the answer you are looking for. At recent MatchMaker events the TNT Infused has been doing well and much better carry wise as compared to the original. For me, we went a touch more depth in the finger holes to create slightly more length (2 1/8 to 2 3/4). The reason for this change is the original TNT (layout the same) burned up for me which had an impact to carry. Initally I thought the TNT was going to be a staple in my bag, but could not get there with surface changes etc. The Infused has defintely been a tremendous upgrade and proves what a tweak to the coverstock can do. Overall, I feel the oob finish is much better on the TNT Infused and I will continue to test for a period of time. The original TNT was a tad strong and the cover dominated a tad to much for some players. Just to note, in my area the lanes tend to be older surfaces and get "sparky" fairly quickly. The TNT Infused has its place as that control piece for this type of situation. The TNT Infused will work best on medium volume patterns. If your desire is to have control downlane the TNT Infused is worth taking a look or even second look at it. I was pretty shocked how much better it looked in its 2.0 version. Don't hesitate to try out the TNT Infused. Please be sure to visit your favorite pro shop today or for more information. Michael Slatky 900 Global Staff Member York, PA

PAP 5” Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at release 17 Review: I like my Original TNT and always could see a use for a polished pearl or Hybrid version, and now we have it! The Infused Hybrid read the lane earlier than I expected which gave me more hook than I thought thus making it a strong benchmark shiny ball. I used this ball in league when my Exotic was too strong and I had control and a lot of strikes. I since have been practicing with it and I am becoming more comfortable and impressed with this ball. The TNT Infused has an explosive punch at the pocket. The TNT Infused fits between the Exotic Gem and the Electrify in my line up. The Infused is responsive to friction but does not over react. This is a good looking ball and as more get out on the lanes I think it will be very well received by all bowlers. I would not call the TNT Infused an angular ball because for me it provides a powerful controlled motion throughout the whole lane. This ball hits great and carry is very good even on off hits. The TNT Infused is very versatile and could even cut down on how many balls you need to carry to the bowling center. Summary: The TNT Infused is a great looking Hybrid ball. The TNT Infused has a strong benchmark motion. The TNT Infused is versatile and has explosive hit. Glenn Wendel Storm Pro Shop Staff Video Link:

    Magic Gem: The Magic Gem is the strongest ball I currently have in my bag. We see plenty of overall motion with this ball as it reads the kids very strong and continues very well. This ball is designed for those heavier oil conditions or when they're absolutely walled and you need the ball to get ramped up early to fight those tighter conditions. I see myself using this ball more on sport conditions versus house as I typically need a cleaner reaction on house to blend out the pattern more which provides additional miss room. For those who liked the X3 from Roto Grip you will enjoy the Magic Gem. TNT Infused: The TNT Infused is an excellent benchmark symmetrical ball to throw when the fronts begin to hook early yet provides tons of mid lane read. The Infused will be more usable for most players against the original TNT as it provides much more back end reaction and doesn't see the fronts as early as the original. I have found success using the TNT as a step down off my stronger balls like the Magic Gem, Eternity PI and Xponent. I am a big fan of this ball as it provides plenty of usability when I need to open my angles up on those medium to higher volume patterns. The Infused will be good on varying patterns from house to sport.

    Layout: 5 x 3 x 5 Surface: Reacta Gloss The TNT Infused brings back the Torpex Core with the new Etrax Plus Hybrid Coverstock. I was pretty skeptical about this ball initially because of how early and smooth the original TNT was. It made the ball pretty pattern specific for me. The new TNT Infused with the Reacta Gloss finish really made a big difference. I went with an opposite drilling with the infused (pin down) compared to a pin up in the TNT just to see a difference in overall ball shape. I was glad that I did. I got to test this ball on a 44ft Typical House shot and a 42ft 32ml sport pattern. On the typical house pattern, I saw clean through the front with a strong midlane roll and ample continuation downlane. It is a ball reaction I enjoy seeing with my higher speed and high rev rate style. On the fresh, the responsiveness of the ball made carry a little tough as some shots got too far down the lane and others were too responsive off the friction. Taking the reacta gloss off the cover would allow me to use this more on the fresh. As the pattern started to develop, the ball naturally started to be more in its comfort zone. The strong midlane roll allowed me to be further away from the friction which is my strong suit. This allowed me to miss more in the oil and not over hook as much when I got the ball to the friction a little sooner. It blended the lanes quite well the further left I got with my feet. I do recommend this ball more as a transition ball for most styles unless you add surface to the cover because then it would be a little smoother for the fresh. If you liked the TNT and want a similar ball with more pop down lane, this would be a no brainer ball. In my opinion, the Infused can be much more versatile then the original TNT. On the 42ft Sport Pattern, it gave very similar results as the house pattern. The Reacta Gloss made it tough to use on the fresh as there was too much length out of the ball. As the lanes broke down and I needed more length through the front part of the lane, I saw great shape in the midlane and good continuation through the pins. This Infused is definitely a good 1st and 2nd transtition ball. I can honestly see myself having two different drilled ones in my bag for medium length oil patterns. I was pretty impressed with the overall shape of the ball and its continuation despite how smooth the original TNT was for me. I believe for most styles, this ball would be a good first transtition ball for medium to medium heavy oil. I think too much oil may give this ball problems as well as the lack of oil as well. Altering the surface by removing the reacta gloss would certainly help this ball work in other environments. I do think its continuation will make this ball work for many styles.

    The TNT Infused features a cleaner, more responsive cover on the original TNT weight block. While the TNT was round, slow and early, the Infused is cleaner and tips more, while still remaining familiarly smooth and controllable. If you're looking for a clean benchmark ball that fits right in the middle of the bag, then the Infused is the ball for you!

  • Roto Grip TnT Infused Review

    Posted by Tobias M on Oct 15th 2023

    The TnT Infused is the newest release from Roto Grip and a hybrid version in the TnT line. The Infused is clean and gets through the front of the lane with plenty of pop down lane. For me, it was quick off the friction but more of a smooth quick. By this I mean when it sees the friction it hooks but does not look like someone kicked it, it is a more smooth response off the friction. Comparing the Infused to the original TnT, the TnT is much earlier and stronger than the Infused. The Infused is a good ball down from the original TnT. Compared to the DUO, the DUO is stronger and reads the lane earlier than the Infused. The DUO has a similar smoother motion when it sees the friction but is not as quick as the Infused and would consider the Infused a ball down from the DUO. This ball is clean through the fronts and controllable off the friction which is a great combo for any ball! Tobias Myers #RotoGrip

  • Great Compliment

    The New Roto Grip TNT Infused, Symmetrical Hybrid with Reacta Gloss is much cleaner than the original TNT. This ball gets down lane with plenty of backend motion. It will be a great compliment to many balls like the DNA, Phaze2, Xponent or TNT. When those balls pick up too quick you can jump right to the Infused and not have any issues getting the ball thru the fronts. I am sure for anyone who feels the ball gets too long, hit it with 2000, 3000 or even try Storm Smooth Edge Premium Finishing Product. I did that with my Absolute and it made a huge difference.
