Roto Grip RockStar Bowling Ball

So far so good. Had to put some power edge on it to get down the lane. Really close to a Phaze II. Will be taking it to Nationals.

Layout: 40 x 4 3/8” x 35 Take the Storm Phaze II and make it a touch cleaner through the fronts, and you have the Rockstar! While that may not sound like it would make a big difference, I have found the Rockstar to be much more playable on a regular medium oil league pattern than the Phaze II. The Rockstar certainly has enough traction to be able to be used on medium/heavy patterns, but the usability on standard medium oil patterns is what makes this ball stand out. It has a good amount of heavy mid lane roll while not burning up too much energy. It is a great step down from the aforementioned Phaze II, or something like a Sublime Focus.

LANE CONDITION Length: 43' Volume:Medium/Heavy Type: THS COMMENTS Layout: 3 3/4 x 4 3/4 x 2 Website: The Roto Grip Rockstar is a recent addition to Roto Grip's HP3 line, designed to offer bowlers a versatile option on medium to heavy oil conditions. It features the new NanoStar™ Solid Reactive coverstock and the ROCKER™ Core, both engineered to provide a unique ball motion and reaction.​ Coverstock and Core: The NanoStar™ Solid Reactive coverstock is a new formulation that bridges the gap between Roto Grip's MicroTrax™ and eTrax™ materials. This coverstock offers strong midlane traction similar to MicroTrax™ but with increased responsiveness to friction downlane, providing a smoother and more controlled backend reaction. The ROCKER™ Core, enhanced with A.I. Core technology, is designed to centralize the rotation plane, promoting better continuation through the pin deck. ​ My Take: Wow! holy flare and control RotoMan! Playing the track 14 -10 - 6 board. My comfort zone. Drilled mine stronger than my Subline Focus and Optimum Idol (4 1/2" pin to pap) which have a more forward pronounced roll. This ball has a more defined motion for me in box finish. I may have to take cover up to 3000/4000 abralon for my lower revrate to get a full 3 games. I tested it against my Axiom Solid and they have similar motion up to the midline, but I feel the A.I. tech gives it an edge going to the breakpoint and pin deck. The Nano cover in my opinion is just as strong an NEX solid. I did try to open up my angles, but it was better playing tighter for me. Great game one on the fresh THS choice. Depending on your speed and lane typography/transition you may get 3 full games with the OOB cover. Still smooth and predictable with that midlane control. I suggest altering the cover for a wider range of use. Performance: Overall I give this an 8.5 for now. Hopefully this will be my Idol replacement for in my bag for a long time. The Roto Grip Rockstar is a solid benchmark ball that offers control and predictability on medium to heavy oil conditions. All styles welcome! #SquadRG

Rock Star - Ball Specs Cover Stock: Nano Star Solid Reactive Finish: 2000 Grit Abralon Rocker. Core Layout: 65 x 5 x 35 RG: 2.48 Differential: 0.050 Review The new Roto Grip Rock Star has the new Nano Star cover stock wrapped around the new rocker core with AI technology. The Rock Star’s RG is 2.48 with a differential of 0.50, which makes it a little earlier than the Optimum Idol Solid and smoother on the back end. This consistent reaction will be great of medium oil patterns (house patterns). It will perform at a high level in the track area and out to the gutter. This ball is a must have for league and tournament bowlers. Now available for order at your local pro shop! My ball reviews are posted on YouTube channel Stanley Waite.

The Rockstar from Roto Grip is the newest addition to the HP3 line and it’s very, very good. I recently competed in the World Series of Bowling in Reno and I was able to use this ball on each pattern with varying lengths between 38’ to 47’. Our masterminds in Utah developed a new NanoStar Coverstock along with a new ROCKER core. There’s A.I. core technology that now gives players an extremely smooth but continuous shape that most players strive for. I’ve drilled two so far and really like both. They both have very similar layouts (5.5 x 4.5 x 1). The CG is just under my ring finger but the pin is “tall” above my ring finger. The biggest difference between the two layouts is the surface. I shined one with the Storm Power Edge polish and hit the other one with a 1000 pad. They compliment each other super well and I know these can be successful on a multitude of patterns. The Rockstar is a perfect ball to use after the IonMax and Origin do their job, but before you’ll need to get into a Road Warrior or HyperDrive. This ball will be in my league and tournament bag for the foreseeable future and I’m excited to have the opportunity to use it! Go drill one!

The Roto Grip Rockstar is a good benchmark for medium oil patterns! The 4 x 4 x 2 layout seems to be working well for you on medium oil patterns. It's impressive that the Rockstar handles the mid-lanes transition effectively while storing power for the back end. Being able to play multiple angles, whether it's a direct line to the pocket or creating shape from right to left, gives you a lot of versatility. The way it throws pins around the pin deck effortlessly must be quite satisfying to watch!

The Rotogrip Rockstar is that strong symmetric solid everyone needs in their bag. The layout that is used is 60 x 4 1/2 x 30 which is a standard benchmark layout for myself. This ball has been thrown on every road trip I have been on this season!

The new Roto Grip Rockstar features a new core in the Rocker A.I. wrapped in a new coverstock, the NanoStar solid reactive. At 15 pounds the Rockstar has a low RG of 2.48 and a differential of .050. and a finish of 2000 grit abralon. This ball is the benchmark symmetrical reaction I have been missing in my bag for some time now. The Rockstar does not read as early as the Optimum Idol did but is not as quick in response time to the Hustle line or other pearl symmetricals. This is one of those balls, that I like to say won’t wow you anywhere but on the score sheet. It isn’t the most hooking ball, or the most skid/flip backend reaction. All it does is control the lane and give outstanding, consistent ball reaction and pin carry. The Rockstar is the perfect ball for medium to medium/heavy oil conditions. It is very controllable and readable and will work from many parts of the lane depending on the style bowler. This is a ball that will give you a lot of use on many different lane conditions.

Rotation 50. Speed at release 17 Review: I am very happy with the new Roto Grip Rock Star. This ball is one of those that I can use when the shot is demanding due to its forgiving nature and the way it seems to find the pocket. The Rock Star fits right between the Hustle X-Ray and the RST Hyperdrive in my Roto line up. The Rock Star reminds me of an earlier rolling Phase 2. The Rock Star rolls up just early enough and just keeps coming with a strong smooth motion. The Rock Star has a powerful controlled motion throughout the whole lane. This ball hits great and carry is excellent for a smooth ball. I bowled on a difficult slick lane condition for the video with the Rock Star and it preformed great, struck a lot, and I had the feeling I could strike all day with it. I feel the Rock Star could be a great fit for most bowlers and styles giving a good amount of hook and forgiveness. On our oilier house shot when I need a ball with more bite but control the Rock Star has been excellent. This ball is finally catching on at the shop and we have seen an increase in demand for this ball. Box finish is my choice for this ball. Summary: The Rock Star is becoming one of my go to balls right now. The Rock Star has a very strong continuous motion. The Rock Star works great on our house shot and should be great on sport patterns as well. Glenn Wendel Storm Pro Shop Staff Video Link: gwendel@comcast.net www.stormbowling.com

The layout on my Rockstar is 55 x 4 1/4 x 20. The Roto Grip Rockstar is a great additional benchmark for medium oil patterns. I know that this will be one of the first out of my bag that I can go to show to provide me versatility and predictability on fresh oil conditions. This is a step down from the Optimum Idol. Since the Optimum Idol is earlier and smoother, with the new Nanostar coverstock, the Rockstar provides more downlane motion, and the Rocker core provides more great continuation through the pin deck. This ball allows me to play multiple angles, such as playing a more direct line to the pocket, or create shape from right to left. This ball definitely goes with me everywhere and is actually fun for me to roll! - Devon R. Storm Amateur Staff
