Roto Grip TNT Infused Bowling Ball

(38 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.

    Roto Grip TNT Infused Coverstock: eTrax PLUS Hybrid Reactive Core: Torpex Factory Finish: Reacta Gloss Layout: 4 x 6 x 4 The new Roto Grip HP3 ball is the TNT Infused. 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.

    LANE CONDITION Length:43 Volume:High Type (THS, Sport Pattern etc):THS COMMENTS Ball: Cover: eTrax™ PLUS Hybrid Core: Torpex Core Finish: Reacta Gloss RG: 2.47 (15lbs) Diff: 0.052 (15lbs) ME: Right-Handed Tweener Speed: 12-13 mph Rev Rate: 315 Axis Tilt: 14° Axis Rotation: 74° PAP: 5 1/8 R 7/8 Up Ball Layout: Pin under bridge 5 Inch Pin to Pap 4 1/2 Inch Pin Buffer Roto Grip's new HP3 release is called the TNT Infused. 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 TNT Infused Cover: eTrax Plus Hybrid Reactive Core: Torpex Core RG: 2.47 RG. Diff.: 0.052 Finish: Reacta Gloss Roto Grip’s new TNT Infused is a Hybrid (2/3 Pearl, 1/3 Solid) Symmetrical piece that is good for Medium-Heavy Volume Patterns. PAP is 5 5/16 R 1 3/16 Up. Rev Rate: 400. Speed: 16.5. Drilled this piece with the Pin above the bridge, CG kicked out 1” from the palm. I threw this piece on a fresh 42’ House pattern. Out of Box ball motion was smooth through the fronts with a hockey stick Motion on the backend. I compared this piece to the Roto Grip Magic Gem (Asym), Clone (Asym), and Hustle USA (Sym). Magic Gem 2-2 Left but started early in the mids with a smooth backend. Clone was similar line as the Magic Gem but a few more on the backend. Hustle USA was 3-3 Right and is smoother on the backend. This piece fits between the Magic Gem and the Hustle USA. Check Out the Ball motion Video on my YouTube Page:

    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

    Ball Specs: Roto Grip TNT Infused Cover: ETrax Plus Hybrid Reactive Symmetric Core Finish: Reacta Gloss Polish Layout 4.5 x 5 with 2-1/2” Pin Buffer Bowler Specs: Right Hand. 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

    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.

    Ball Specs: Roto Grip TNT Infused Coverstock: eTrax™ PLUS Hybrid Reactive Weight Block: Torpex™ Core Color Glow Orange / Copper / Plum Finish Reacta Gloss™ Layout 45x4 1/4x40 or 4 1/4x4x2 1/2 Bowler Specs: Right Hand. PAP 4 3/16 Over 1 1/16 up Rev Rate 400 Speed at release 17.5 Review: The TNT Infused is the new ball in the HP3 line. This is a hybrid version of the TNT featuring the eTrax plus cover stock and the Torpex core found in the original TNT. This ball is going to be a later rolling and more backend version of the TNT. If you found the TNT to be too early then this will be a great compliment. eTrax hybrid is a two part pearl one part solid cover, mine seemed to be mostly pearl in my track which gave me a more length but each will be different pours. This ball is going to be a good transition ball on breakdown when you need to stand a little left but need the recovery to the pocket. For higher rev rates the Infused can be a great benchmark ball with surface or a ball that you can get left with. For lower rev rates and higher speeds this will be the ball you will go to when the lanes start to get burnt up. Get yours November 3rd at your local Storm VIP pro shop.
