Roto Grip RockStar Bowling Ball

Roto Grip Rock Star My updated specs: Rev rate 420’s, ball speed 15.3 to 15.8 mph off the hand, axis tilt of 16 degrees and axis rotation of 70 degrees, PAP is 3 15/16th up 3/16th. Tested on Pro-lane surface on a 44 ft house pattern with lower volume used for the junior and senior leagues, a 44 ft house pattern with larger volume, and patterns that ranged from 33 ft to 39 ft sport patterns. Color: Crimson/Jet/Maroon Core: Rocker + A.I. Core Technology Coverstock: NanoStar Solid Reactive Finish: 2000-grit Abralon Layout: 2 x 6 x 1 RG: 2.48 (for 15# ball) Differential: 0.050 (for 15# ball) Recommended Lane Condition: Medium to Heavy Oil The all new Roto Grip Rock Star has been a BEAST on the lanes in league play for me in the past 4 weeks. The motion is very easy to read, not jumpy, humpy, or bumpy. Stronger than my Roto Grip X-Ray with identical layout, but more length and not as quick to jump off the pattern as my Optimum Idol with a similar layout of 3x6x1. Similar in overall performance as a Hyped solid on fresh, but as the pattern breaks down, the Hyped Solid would be put away, the Rock Star stays on the rack for all 3 games. The only other ball in recent memory like this is the Storm Equinox, where just making small adjustments allows me to stay in the ball longer and not have to deal with a ball change so quickly. The lowest league match has been 696 and the highest was 778, my current average is 212. The Rock Star is what I call a “keeper” where one will be in my league bag and as bigger tournaments are on the horizon, a second Rock Star will be drilled for tournaments. Current league bag is now as follows - Rock Star, Equinox, and Attention Star S2. Now only bringing that ONE back to league - because these 3 balls cover everything I need in league.

Roto Grip Rock Star Coverstock: 2000 Grit NanoStar™ Solid Reactive Weight Block: Rocker™ A.I. Core (Symmetrical) Color: Crimson/Jet/Maroon Review: So glad the HP3 line is getting a new core and cover. We expected this ball to be smooth and have some similar characteristics to the Optimum Idol. Our style: tweener, 350-375 revs, 16.5mph, layout of choice is 4x4x2 (pin is above bridge). This ball is incredibly clean, way cleaner than we expected, and likes oil in the fronts. This is typically not a ball that would be first out of bag for us and is probably better characterized as a specialty piece, or maybe a ball that is better suited for tougher patterns where you have to kind of jam it up the right side and keep your angles straighter. If you do like to swing it you may need to add some surface to get it to read a little earlier. For us this ball would look better on fresh or a house pattern if we brought the surface to 1500 or 1000 to try and get rid of that cleanliness through the fronts. Overall this ball Rocks if you need that piece that goes straighter in blocks or if you find yourself struggling to find a ball that is very clean and very smooth.

The new ball in RG HP3 line is the Roto Grip Rock Star. With all new NanoStar™ coverstock material is our latest nanotechnology remix and with the new Rocker core and A.I. Core technology. My feeling the intent from Storm HQ was to develop a benchmark ball in the RG line, similar to say a Storm Phaze 2. I drilled mine 4.75x4x1.75 pin up. Man all I can say is this ball just strikes. The cover is a little on early side like a phaze 2 but it has very good response down lane. Its a very strong arc motion, and just goes through the pins amazing. I was fortunate to shoot 300-804 off the press with the Rock Star on a 46ft modified house pattern. I played up the lane around the track area. If I leaked it to the dry it just stood up and rolled a little forward and still went through the pins. If I missed in a little in the puddle it was still strong enough to respond down lane. I keep the surface around 2000 abralon. Very good bench mark ball. Its stronger than overall than the IDOL line to me but it different parts of the lane. It has more pop off the friction down lane than the IDOL. Not quite as strong as the bigger asyms like Attention Star S2 or ION Max. But stronger than Summit Ascent or the ION PRO. Great Ball period and a must for everyone's arsenal.

Mine is Pin down, in my ring finger, out of the box, 759 with a 289 (10 pin) yeah, I love how this ball rolls. AND YES...you can watch this ball roll and read the lane like no other. I had no skid flip with this ball, its nice and smooth, and like I said really easy to read and really easy to move off of. Is there anything better? I keep it at box finish and very excited to throw it. I can't wait to try it on some sport patterns. It's just an easy ball to throw and a ball to read. It's a heavy/medium oil ball that rolls. The new Rock Star is amazing!!! I love it!

I picked up the Roto Grip Rockstar in 14 pounds, and it’s been great on medium to heavy oil. The Rocker Core (RG 2.50, Diff 0.046) and NanoStar Solid cover at 2000-grit give it a smooth, steady roll. It moves cleanly through the fronts, picks up in the midlane, and arcs into the pocket without any sudden jumps—just predictable control. The crimson/jet/maroon color scheme looks great, nothing too wild. On our house shot, it handles oil well and doesn’t overreact on drier spots. I’m a mid-rev bowler (around 325 RPMs), and it fits me perfectly. Swinging it wide, it comes back fine, though it’s not a sharp backend ball. That’s more my preference anyway—less aggressive than some big-hook options. It reminds me of my Optimum Idol, but it’s cleaner and doesn’t grab as early.

Rockstar Ball Review Layout-VLS 5x4x2.5 Surface-2000 Grit RG-2.48 Diff-.050 Symmetrical Core Roto Grip Rockstar features and new core called Rocker with AI Technology wrapped with the new Nanostar Solid Reactive Coverstock.The Rocker core is a low rg symmetrical weight block which produces a very continuous but predictable ball motion. The new Nanostar coverstock will fall between Microtrax and E-Trax base coverstocks.The Rocker is a very versatile ball which will allow you to play straighter or move left and create more angle. The Rockstar will fall in the strong benchmark category. I compared the Rockstar to the Optimum Idol Solid,X-Cell and Attention Star S2.The Rockstar compared to the Optimum Idol Solid will be cleaner with a sharper move on the backend. I feel like the Rockstar will be fall below the Attention Star series and X-Cell and above the Idol series balls. The Rockstar is available Feb 21st!!!!!!!!!!!!

I’ve been looking for a symmetrical medium to strong ball from SPI that would be more versatile than the Optimum Idol. I believe I’ve found it in the new Roto Grip Rockstar. The Rockstar features a brand new coverstock called NanoStar that has the nano particles found in Roto Grip balls. The particles always help with traction to bite into the oil pattern. The new NanoStar cover fits between the MicroTrax (on Optimum and RST-X1) and eTrax (Attention Star, S2, X-Cell and RST-X2) covers. As a result, it’s a little cleaner through the front than the Optimum Idol and more versatile depending on whether you shine the Rockstar or hit it with some surface. The Rockstar also features a brand new AI core called the Rocker which is a strong symmetrical core that provides more continuation through the pin deck. Bottom line, this is a great ball that can fit many spots in your bag from the strong side to the clean side of the middle of your bag and everywhere in between. I drilled mine pin up, 4 ½ from my PAP.

The Rockstar is Roto Grips newest HP3 ball. The Rockstar has big shoes to fill with the recently discontinued Optimum Idol. The Rockstar features Nano Star solid wrapped around the Rocker AI core. The Rockstar is slightly cleaner and quicker than the Optimum Idol. The Rockstar for me is fairly close to the Storm Phaze 2. The Rockstar is now available for purchase from any Storm VIP Pro Shop!

TESTING ENVIRONMENT Length:42 Type (THS, Sport Pattern etc): House Shot BALL: Roto Grip Rockstar Coverstock: NANO Star Solid Core: : Rocker A.I. Core Finish: 2000 Grit RG: 2.50 (14 Pounds) Differential: 0.046 (14 Pounds) MB/PSA: NA (14 Pounds) ME: Right-Handed Tweener Speed: 13-14 mph Rev Rate: 210 PAP: 5 1/2 right 1/4 up Ball Layout: 4.5x3x2 This might make anyone drop the mic! I want to first mention that the Rockstar and the Attention Star are not in the same line even though they share the “STAR” name. I have been struggling at one of our centers with the cliff that forms just after practice. It really tamed the over/under or cliff that I have had a hard time with. This ball makes you look like a Rockstar with the right amount of everything that has been done with this ball. As a ball from the HP3 line with surface to me it picks up much quicker than other balls you would think of like the Idols which were much slower. Over the past couple of weeks this ball has really shined and has made my bag that goes everywhere. This ball has a WWRD 2/21/25 Thanks for reading & watching and if you like this or any of the jerseys in my videos just head over to www.IAmBowling.com and use HIRSCH at checkout for 20% off.

I drilled the new Roto Grip Rock 5x4x2 to give me a nice smooth motion. This ball is a new core/cover combo with nanoStar solid wrapped around the new Rocker A.I. Core. This ball fits in the optimum idol category as far as reaction goes. This ball will give you a nice early motion but still retain enough energy to continue through the pins. I plan on this ball being the 2nd ball out of my bag in tournaments to combat those heavy volume patterns. For leagues, I'd recommend hitting this ball with a 3000, 4000 or even polish to keep the ball from burning up too early. This ball works great for me! I highly recommend!
