Roto Grip Clone Bowling Ball

(24 reviews) Write a Review

CLONE - "a thing that duplicates, imitates, or closely resembles another in appearance, function, performance or style." And well, since the last version of this core part was unwillingly abducted, we felt it was our responsibility to the entire bowling galaxy to "clone" it and mix in a few upgrades & performance enhancing tweaks that bowlers of all skill levels on planet earth will benefit from. And just as before, the reasons that led to the creation of the original E.T. Core that featured out of this world core technology better known as “equalizer cavities” to emulate the use of a balance hole, the CLONED E.T. Core also does that, but MORE. Yes, you read that correctly, the same.

In our pursuit of creating out of this world ball motion, we felt it would be beneficial to all bowlers on earth to reimagine the proven E.T.™ Core (Equalizer Technology Core) in order to best complement all of our other asymmetrical cores. By simply changing the density of this single piece part, it not only lowered the RG values of the 16lbs – 14lbs options, it also, increased the Differential values in those parts as well, thus increasing the overall motion potential. So, what does all of that actually mean? It means more overall midlane and downlane motion than the previous version of this core thanks to the increase overall dynamics and the benefit of the built in “equalizer cavities.” And just as before, the more effort focused on core placement before drilling, the easier it is to dial in the desired ball motion.

Based on years of testing and research, we found this direction of coverstock chemistry provides a more balanced oil displacement/absorption throughout the entire lane thus creating more consistency/predictability shot after shot in terms of skid distance, midlane traction, and response to friction down lane. Derived from the advancements of both the eTrax™ and eTrax™ PLUS solid materials the last couple years, we found this new direction of solid material that complements both of those without overlapping them. Because variety is the spice of life, especially here on planet earth.

    Roto Grip Clone Cover: OptiTrax™ Solid Reactive Reacta Gloss Weight Block: Cloned E.T.™ Core (Asymmetrical) Color: Alien/Deep Mist/Cyber Grape Review: First off, the colors on this ball and logo are awesome and look SOOOO good in person with the reacta gloss (major shelf appeal). We drilled this ball with our normal layout: tweener, 350-375 revs, 16.5mph, layout of choice is 4x4x2 (pin is above bridge). This ball is pretty comparable to the UFO line if you had one of those pieces. If you didn’t, you can expect a clean ball motion through the front and mid parts of the lane. The reacta gloss finish is perfect for an immediate ball down from a strong Asym piece when starting out on a fresh block. If we were using this on the fresh we would probably knock the reacta gloss off and go with a slight bit more surface to blend the lane a bit. Overall this ball looks great on the lane and on the shelf. Go pick up your Clone today! Kyle, Joel, & Dean Johnson Roto Grip Pro Shop Staff Members #SquadRG

  • The Clone - It comes (back) in peace, but strikes at will.

    Posted by Todd Sigeti on Sep 4th 2023

    Layout: 5.25 x 3.5 x 2.75 The new Clone is the latest asymmetric piece in the Roto Grip line. Compared to the current high-performance asymmetric offerings (Gem and Exotic Gem), the new Cloned ET Core has a higher RG (2.51 at 15 pounds), allowing it to lope a little further down lane and get through the fronts a little better. With a high differential and PSA of .056 and .016, this has a ton of hook potential in the midlane and the back end, and especially for a solid asymmetric, it gets kicked in the teeth when it makes its move. This ball combines the new Cloned ET Core, which is a modified version of the core found in the UFO and UFO Alert. The RG is slightly lower in 15 pounds (2.52 vs. 2.51), and the differential is slightly higher (.054 vs. .056). What's the result? More of a continuous motion on the backend than the UFO Alert, but earlier roll and motion in the midlane. The UFO, with its dull solid cover, was more like the Hyper Cell from nearly 10 years ago--the Clone is very reminiscent of the Eternal Cell from about 8 years ago. On the THS pattern that they put down during league, this is a very versatile asymmetric that I could see using at any point in the session. Its dynamics allow for a straighter starting angle with a big, but predictable, move on the backend after getting it to the outside dry, but also for playing the puddle in the middle. Due to the Reacta Gloss finish, it maybe be beneficial to take some of the shine off of the ball before playing in that oil, but your results may vary. This is going to be a great piece for the 1st or 2nd transitions during tournament play. In pro shops now! Todd Sigeti Storm Amateur Staff

Built with the "Cloned" ET (Equalizer Technology) Core and Optitrax Solid Reactive Coverstock, the Clone takes its predecessor's success to a whole new level of pin-crushing results and is the next-generation powerhouse. So, let's get into what makes the Clone a must-have for your arsenal. The heart of the Roto Grip Clone is the Cloned ET Core. And we can talk about the design and all the technological jargon. But let me put it into terms we can all understand. The Cloned ET core is a smooth rolling powerhouse ready to unleash its wrath on anything that gets in its way, period! Further, I liked how the Cloned ET core revs in the mid-lane for a strong Asymmetric Core without being lazy. And it generates plenty of that stand-up and delivers power when the Clone exits the pattern. And when the Cloned ET gets into its roll phase – watch out! The Cloned ET Core has relentless power as it explodes at the pocket and steamrolls through the pin deck. So, if you are a straighter player like me, you can count on the Cloned ET Core to deliver when you need it most. The Optitrax Solid Coverstock worked OK for me with the Reacta Gloss box finish. But because of my low rev rate and down and in style, I needed more bite and a smoother transition that Reacta Gloss finish provided. So, I sanded the Optitrax Solid with 1500-grit Abralon, and the results were excellent. On a THS, I liked how the Optitrax skates in the front part of the lane and gently bites in the mid-lane, providing a smooth and predictable motion I could count on. Whether early on fresh conditions when I am playing straight up second arrow or later in game three when I need to open my angles, I could rely on the Optitrax Solid to deliver a clean and brisk transition off the pattern without worrying about the Clone jumping when it finds friction. So, if you are a down-and-in player like me, the Optitrax Solid will perform nicely for you with the correct surface adjustment to fit your game. So, in conclusion, the Roto Grip Clone goes beyond where its predecessor left off and is an excellent new release. And although it may be "Cloned," I found the Clone to be the next generation that stands on its individual merit and is a powerful weapon to fit your arsenal. So, if you are a down-and-in player who relies on the strong angular back-end motion to deliver results, stop by your local Storm VIP Pro Shop today and have your Clone ready for action when your league play begins! You will love the results! Rick Klimowicz Storm Products Pro Shop Staff Roll the Ball Pro Shop Penndel, PA

  • New version of the E.T. Core

    Posted by Dave Adams on Aug 27th 2023

    Roto Grip Clone ball review The Clone is another ball that gives me a shape different than anything in my bag right now. As I was a big fan of the E.T. Core, getting a new piece using a revised version of it was something to look forward to. Combined with the Optitrax solid cover with a Reacta gloss finish and you have a great new addition to any arsenal. This ball is plenty clean through the front of the lane thanks to the Reacta Gloss. It really shines (no pun intended) in the midlane. The Clone really picks up for me there and makes a really strong move, even on heavier oil. The ball is pretty forward on the back of the lane, making it very controllable. If you play more up the lane like me, this will really make this ball usable on a variety of conditions. It gives me a good angle to carry while not going sideways if I miss a little. Whenever I used it so far I have seen some big scores. I also find it easy to read the lanes with it as it makes that very defined reaction in the midlane. With the Reacta Gloss finish, this ball is much cleaner and sharper than any other solid covers I have right now. It's a little less overall than my Summit, but stronger than my go to pearl which is the Eternity usually. This ball should be a great addition for fresh oil, or when you need something strong but not too early. If you were a fan of the UFO Alert, you will definitely want one soon. Dave Adams Storm staff

  • Roto Grip Clone Ball Review

    Posted by Patrick Keiffer on Aug 26th 2023

    The Roto Grip Clone has a low RG value of 2.51 a high differential of 0.056 and a high intermediate differential of 0.016. Roto Grip came out with a brand new cover/core combination of the Optitrax cover and E.T.™ Core (Equalizer Technology Core). To bring this all together the Clone will give you something that you can get deep inside and blend out the wet/dry lane conditions. The Optitrax cover which has been derived from years of testing and research to provide a more balanced oil displacement/absorption throughout the entire lane thus creating more consistency/predictability shot after shot in terms of skid distance, midlane traction, and response to friction down lane. Derived from the advancements of both the eTrax™ and eTrax™ PLUS solid materials the last couple years, we found this new direction of solid material that complements both of those without overlapping them. The proven E.T.™ Core (Equalizer Technology Core) as seen in the UFO series, to be a complement all of our other asymmetrical cores. By simply changing the density of this single piece part, it not only lowered the RG values of the 16lbs – 14lbs options, it also, increased the Differential values in those parts as well, thus increasing the overall motion potential. In comparison to the Roto Grip Gem, the Clone will be a cleaner option to be used on the fresh that will be a step down from the Gem but to be used in that heavy oil place in the bag especially on the older lane panels. In addition, the Clone will be a pliable and very versatile coverstock that will take kindly to surface adjustments. In the bag, will be the Clone, Summit, Xponent, Zen Gold Label and Hustle RIP.

    Roto Grip Clone: Cloned ET core with Optitrax solid reactive cover. Layout: 50 x 3 ½ x 35: finished with Storm Reacta Gloss. With the recent change in my game and health, for the better, I wanted a good and strong solid reactive mid-length with little less flare than the other 3 new balls I had drilled. We went with the above layout. The initial few throws were stronger and heavier through the pocket than my Exotic Gem, I needed to open up and swing it a little more and open up the pattern and lane. After practicing for 30-35 minutes with the Clone, I became comfortable with the strong roll and blistering through the pins. My friend and 900 Global staff member could not believe how well the Clone rolled and reacted for me. The Exotic Gem is not as strong as the Clone for me, and I feel it rolled and performed better than the OG UFO and UFO Alert. Used the Clone and Tour Dynam-X exclusively since getting these balls in my hands. If you need that new medium to heavy “oil” ball the Clone is out of this WORLD and should be used by every smart league and tournament bowler.

    Roto Grip Clone Coverstock: OptiTrax Solid Reactive Finish: Reacta Gloss Core: Cloned E.T. Core (14 pd) RG: 2.53 Differential: 0.056 Int Diff: 0.016 Layout: 5 x 5 x 4 2LS Tester: PAP 6 1/2 R, 1 1/4 D Review: The Roto Grip Clone is not simply a substitute for the UFO Alert, but rather a beefier redesign. The Clone offers options to handle heavier volumes of oil, more options for various weights and a coverstock that generates a touch more length then your traditional solids. In addition, the Clone provides enough variation in the HP4 line to be part of any arsenal. The coverstock of the Clone along with the updated core compared to my Exotic Gem allows for more length through the front part of the lane. Both of these balls have been a pleasant surprise regarding control. The Clone is more angular and will allow you to open the lane up more for a big asym ball compared to the Exotic Gem. The OOB finish worked well on two older HPL surfaces where the THS shot is oiled at 42' and 43' feet. Initially, I thought I may need to surface with a 1K or 2K pad. For now, I'm leaving the surface as-is. In addition, I have an opportunity to attend some SPI demo days where I want evaluate the Clone in more detail. As indicated above your Clone will work best on longer and higher volume patterns. Do not hesitate to try out the Roto Grip Clone today! Michael Slatky 900 Global Staff Member York, PA

    Orientation: Right Handed Rev Rate: 400 RPM Speed: 16-17 MPH PAP: 4 ½ over and ½ up Location: Enterprise Park Lanes, Springfield MO Pattern: High Volume THS VLS Layout: Layout 1: 5 x 4 x 2 ½ (pin above bridge) Layout 2: 4 ½ x 4 x 4 1/8 (pin below bridge) The Clone is a new HP4 asym from Roto Grip. They modified the UFO Alert core and added a new straight reactive cover. The result is a ball that’s earlier and rounder than the Alert. I was surprised when it was announced as a solid but after throwing it I really really like it. The straight reactive cover doesn’t read the fronts as much as some of the stronger asyms we have so I feel like I can use it on more volume levels and for longer. The core doesn’t super read either either but it does hook quite a bit in the back part of the lane. I would put the clone on the bottom end of our asym lineup in terms of strength in the front part of the lane but overall hook it definitely ranks towards the top with the added bonus of not reading too early!

    Cover: OptiTrax Solid Reactive Core: Cloned E.T. Core RG: 2.51 RG. Diff.: 0.056 Finish: Reacta Gloss Roto Grip’s new Clone is a Solid Asymmetrical High Flare piece that is good for Medium-Heavy Oil conditions. 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, and the Mass Bias 1/2” to the Right of the Thumb. I threw this piece on a fresh 41’ house pattern. Out of Box ball motion was clean through the fronts with a smooth backend reaction. After I took a 2000 & 3000 Abralon, it was still clean through the fronts but a sharper backend motion. I compared this piece to the Roto Grip Gem, Storm IQ Tour, and 900 Global Reality. Gem started earlier and had a smooth backend. IQ Tour (1-1 Right) overall a smooth reaction. Reality started earlier with a strong backend (3-3 Left). This piece will be good for all types of styles. Check Out the Ball motion Video on my YouTube Page:

  • Clone-ing Strikes

    Posted by Chase Valenzuela on Aug 21st 2023

    The Clone is the upgrade we've been needing! The UFO Alert provided a unique shape that was clean and quick but overall pretty rounded. The Clone took heavy inspiration from that. However, it isn't just a reboot. The Clone features a brand new coverstock formula, this time in a solid version. The result is a noticeable step up in cover strength from the UFO Alert, and the modified density of the core provides a clean and stable shape. While the Clone is distinctly mid-RG in that is doesn't wind up and want to hook as soon as it sees friction, the cover and core work well to create traction and store energy. This is the strongest angular asym we've had in the line in awhile, and a surprising improvement on a shape that was a fan favorite.

    Roto Grip’s newest HP4 line ball has a little bit of a different twist on it. The Cloned ET core which features an RG of 2.51, differential of 0.056 and PSA of 0.016, has the new Optitrax Solid cover but this solid is polished with Reacta Gloss. I drilled mine 5.5 x 5 x 5 and after throwing this ball for awhile I was completely surprised by that reaction of it. The Cloned ET core is an upgrade of the ET Core that was found on the UFO and UFO Alert. I thought with that happening the ball will be a little blend between those two balls but to my shock it reminds me of a weaker version of my DNA which I also have Reacta Gloss on. I think the Clone is going to be a house shot killer for any style of bowler and I think tournament bowlers will enjoy the versatilely of having it shinny or taking some surface too it.

  • Take me to your leader!

    Posted by Steven Collins on Aug 19th 2023

    The Clone is a strong ASym that provides you all the backend pop you need. This ball is super angular, maybe a bit too much on a fresh house shot but as the lanes start to transition and you need to move deeper this is going to be my go too ball. No matter how far left I move it still find a way to recover and get to the pocket with enough energy to strike.

    Core: Cloned E.T.™ Core (Equalizer Technology Core) Cover: OPTITRAX™ COVERSTOCK Finish: Reacta Gloss RG: 2.51 (15 lbs) Diff: 0.056 (15 lbs) PSA: 0.016 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 over Bridge 5 1/4 X 4 X 3 VLS The "new" HP4 release from Roto Grip may seem familiar. The Clone is intended to give back the motion that fans of the UFO Alert loved. The Clone ET core and optitrax combo makes for a strong ball with some great down-lane motion. I tested the Clone on the high volume, long house pattern at my home center. The Clone is definitely strong enough to throw on the fresh here. It has turned out to be a great ball for bouncing off the friction even with as heavy as this pattern is. The high diff makes sure you get the flare you need for dynamic motion. The higher RG and clean cover keep it in play as you have to move left in the transition. I definitely feel like this ball likes high volume patterns, but it's no one trick pony. I was honestly a little surprised at how easily I could get this ball through the front of the lane as the night wore on. When I finished shooting my reaction video I decided to experiment with adding friction. I gotta say from a personal standpoint I think I like this ball even better at 2k than I do polished. It's still pretty clean, but smoothing it out a little down-lane was great for me and helped with over/under. I would recommend the clone for just about anyone. It's strong enough for people who need help from the ball to see motion and it's clean enough that rev dominant bowlers can use it on a variety of conditions.

    Posted by Ben Lapointe on Aug 14th 2023

    Ben Lapointe PAP - 1 1/4'' up, 4 7/8 over Layout - 5.25 x 4.25 x 3 The CLONE is the newest installment in Roto Grip's HP4 line. While the words "solid asymmetric" often mean early and strong. This piece for me, is actually very versatile when it comes to length and starting point. It comes out of box with Reacta-Gloss, which really allows it to clear the fronts with ease. A surface change on the CLONE can bring the starting point closer to you and allows it to be 2 or 3 balls in one. It is very round down lane, giving the a lot of control throughout the entire path of the ball. While I have never thrown its predecessor, this seems to be the closest replacement to a UFO Alert that we have in the current line. Go get yours August 18th and remember to bowl up a Storm!!

  • Hooks out of this world

    Posted by Evan Pitt on Aug 13th 2023

    This ball is very angular. After reading up on what SPI was trying to do with this ball, they definitely hit it on the head. Colors look good going down the lane, clears the mids with ease, and comes off the spot with a mission. I only give this ball 3/5 because it doesn't fit my game well. I have seen other have much success with this. I hit mine with a used 2000 pad to knock off the shine a bit, it came to life for myself. It is just too much ball for the shots out here, This is for sure a tournament ball for me.

  • Clone!

    Posted by Josh Shoemaker on Aug 13th 2023

    The Clone features the Cloned E.T. core and is wrapped in Optitrax solid. The Cloned E.T. core is almost a carbon copy for the E.T. core that was found in the UFO series balls. The Optitrax solid cover feels like a slightly milder version of MicroTrax found on the Gem. The Clone is going to be a fantastic option for someone that needs the same amount of traction that the Exotic offers in a rounder package.

    Ball Specs: Clone Cover stock: OptiTrax Solid Reactive Core: CLONED E.T. Core, Asymmetrical Finish: Reacta Gloss Color: Alien/Deep Mist/Cyber Grape Review: The new Clone comes from a long line of successful bowling balls in the HP4 line from Roto Grip. With the new and improved CLONED E.T. core the Clone sees a great mid lane read with more backend motion then you would typically see from a bowling ball with a solid cover stock. This ball was very predictable and I was able to manipulate the shape I wanted to see simply by adjusting my hand and ball speed. I see this ball as a step down when my Summit starts to burn up the lane. I found that the Clone offers me a smoother and more round shape when lanes begin to change how they are playing. The Clone is going to a great option for bowlers of all skill levels and styles. The high rev platers you will see a ball that can get through the mid lane and still have plenty of backend motion, but that will also allow you to move a little further right if you desire to do so. If you are a lower rev bowler you will get a ball that brings plenty of pop without being a ball that can’t control. Make sure you grab your Clone today!

It features the OptiTrax Solid cover with the CLONE E.T. core which is designed to provide more overall midlane and downlane motion than the original E.T. core. The cover/core combination will help create increased shot predictability when looking at skid distance, midlane traction, and downlane response. The Clone is designed for medium to medium/heavy conditions and is the second generation of the UFO/UFO Alert. The Clone gave me an excellent look sliding on 30, looking 18 at the arrows with my breakpoint around 8-9. I was able to easily play different zones on the lane by manipulating my hand position and speed. When compared to the TNT, I was able to stand and look in the same place, but the ball reaction was different. The Clone was cleaner through the fronts and had more downlane motion. If I need the ball to start up quicker and roll more forward, I would use the TNT. I can see the Clone being useful in league and on tournament conditions when the backends get tighter.

    Layout: 5 x 4.5 x 4.5 Surface: Reacta Gloss The new Clone features the enhanced Cloned ET Core which lowered the RG Value and increased the differential compared to the ET Core of the UFO and Alert. This creates a stronger foot print in the oil for heavier oil conditions. There is also a new coverstock on this one with the Optitrax Solid. The finishing process is also Reacta Gloss which is completely new for a solid coverstock since the Eternal Cell many years ago. What makes this finishing process great is that it gives a cleaner look on the lane while giving a more angular and continuous backend than if it were a dull finish. This surface alone will give this ball more usability across more different lane conditions. I was able to test this on a typical house pattern and the 38ft Kegel Alcatraz Pattern. On the house pattern, I found this ball to be cleaner through the front and more angular down lane. The solid coverstock allowed me to still see good continuation and control on the lane good enough for the fresh. The reacta gloss did give it a little more length in the oil at times and did leave a weak 10 pin. When I got this ball to the friction, it read the lane very well and had a lot of hitting power through the pins. Compared to a Gem, the Clone is definitely cleaner and more down lane motion. Knocking the reacta gloss off this ball will bring it a lot closer to the Gem while still being overall cleaner. On the Alcatraz pattern, I found the reacta gloss finish to give me too much length to have success on the fresh. It often finished a little too behind the head pin and was a little too strong if I went more direct up the lane. As the lanes transitioned and gave me more hook to the outside part of the lane, this ball really started to shine. It still gave me easy length but angled more harder than on the fresh. It went through the pins significantly better. As the lanes continued to transition and I moved more left with my feet, the ball reaction still stay strong. It continued to angle through the pins while also controlling the flatter part of the pattern. This reaction is a great thing for my style because it still controls the lane while giving more length and continuation. On medium to medium long patterns, this ball will be in my bag as it is perfect for them. Heavier oiled patterns, would need some extra surface to get it to slow down a little quicker, especially on the fresh. I can also see myself having two of these in the bag, one being shiny and the other dull. Compared to the UFO alert, the stronger solid cover of the Clone makes it earlier and smoother. They can easily play off of each other well if the surfaces are both similar. Adam Chase Storm Staff

    Ball Specs: Roto Grip Clone Coverstock: OptiTrax™ Solid Reactive Weight Block: CLONED E.T.™ Core Color Alien / Deep Mist / Cyber Grape Finish Reacta Gloss Layout 50x4 3/8x35 or 4 3/8x4 1/4x2 1/4 Bowler Specs: Right Hand. PAP 3 9/16 Over 7/8 up Rev Rate 400 Speed at release 17.5 Review: The Clone is the newest ball in the HP4 line for Roto Grip. It is featuring the Cloned ET core which is like the original ET core but has been modified to get a lower RG and a higher diff. With the Clone I found is a ball that is really clean due to the Reacta Gloss. The new coverstock is also a balance of a clean but round shape. With the core you are getting a early rolling core with continuous motion. This ball will be a good step down from a gem but is still a longer reaction compared to an exotic gem. This will be good out of box with higher rev bowlers but will adjust very well with surface to fit a variety of styles. Get yours 8/18 at your local Storm VIP pro shop.

    Ball Review (Dynamo X & Clone): The Tour Dynam-X will be a staple in the bag for some time to come. In this review I bowled on a very light THS that had some recreational play on it prior to me bowling. I drilled 2 Dynam-X balls as I was a big fan of the Rubicon which features a modified core in the Dynam-X. With the high friction/early hook conditions I encountered the pin down provided the best look of the 2 as it blended out the pattern real well. As you will see in the video with the pin up I begin to loft the ball a bit to get the ball to clear the fronts and provide energy down lane. I believe the Tour Dynam-X will be a great benchmark ball to throw on medium to higher volume and will be good with surface adjustments. I saw real good continuation with the pin down as that ball matched up the best, provided plenty of margin and great hitting power through the pins. With the Clone given the strength of this asym and the environment I was bowling on it was way too strong for those conditions. I winded up moving right from the Dynam-X and increased my ball speed to get it through the fronts and provide angle down lane. You will see on the first few shots when I play left to right it read too early and didn't provide enough shape down lane. Once I got right and increased speed the ball looked real good. This will be good for medium to heavier conditions and could be used either on the fresh or as a transition ball off the stronger solids.
