Roto Grip RockStar Bowling Ball

Roto Grip Rock Star Layout: 4.5 x 4.0 x 1.5 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 IKON Kegel Machine – Brunswick Anvilane The Roto Grip Rock Star utilizes the Nano Star solid reactive cover along with the Rocker A.I. Core. The Roto Grip Rock Star was an afterthought for me. I was late to the party to drill one but I am so glad that I did. I have thrown the Roto Grip Rock Star a bunch in the last two weeks. I have thrown it at the Greater Ozarks Tournament, a local best-ball tournament, and in league. The Roto Grip Rock Star has looked great at all three arenas, in different bowling centers that I tend to struggle in. My tournament arsenal (current) 1. Storm Ion Max 2.

Roto Grip Rockstar Cover Stock: Nanostar Solid Reactive Finish: 2000 Grit Abralon Core: Rocker + A.I. Core Technology (14pd) RG: 2.50 Differential: 0.046 Layout: 5 x 4 x 4 - 2LS Layout Extras: 2 1/2" Finger Depth, "X" - 4 1/2 D and 1 Inch Left Tester: PAP 6 1/2 R, 1 1/4 D Review: The Rockstar features a second generation core design with A.I. technology building off of the Optimum Idol. Essentially, this means to the bowler is more length and more motion off the spot compared to previous releases in this category. You'll also keep hearing that A.I. technology provides up to five-percent more carry on off hits. Keep in mind the cover is Nanostar which is one of the more aggressive coverstocks RG offers. The Rockstar is proving as an excellent symmetric option for fresher lanes. We are already witnessing/reading how well the Rockstar is performing at the World Series of Bowling. In addition, working several SPI MatchMaker events the Rockstar is proving to be a great #1 option in the arsenal. A good ball to compare the Rockstar to is the Optimum Idol. For me the Optimum Idol was a tad earlier and smoother. Also, the Optimum Idol for me would tend to burn up early and to the eye not go through the pins the way I ideally wanted on transitioning patterns. However, the Rockstar at the OOB finish is perfectly fine and I'm more pleased than I initially thought from reviewing the specs. To point out the Rockstar minor adjustments compared to the Optimum Idol make this a must have ball. SPI definitely has been listening and made those slight tweaks to give the bowler a better experience. I prefer the the Rockstar smoother shape compared to other offerings. This is due to my personal preference for smoother arc type reactions for tournament play.

The Rockstar definitely provides a new and improved motion and reaction for me that I haven’t seen since the Optimum Idol was released. I did not think I was going to find another symmetrical ball I loved more than the Optimum Idol but I should know better because that’s what this company does, they keep creating banger after banger. The new NanoStar coverstock material might be one of my new favorite coverstocks. It provides similar traction in the midlane to that of the legendary MicroTrax material but does not dig into the lane as early. The Rocker Core provides a more centralized rotation plane to better provide more continuation through the pin deck for all skill levels. This ball has also allowed me to start a little straighter and as the lanes transition I can move left with it and it still plows through the pins. This ball is going to be the Most Underrated Ball of the year. Don’t sleep on the HP3 line of balls.

Ball Specs: Rockstar Cover: NanoStar Solid Reactive Core: Rocker AI Review: The Roto Grip Rockstar is a reliable benchmark ball designed for medium oil conditions, offering a smooth yet strong reaction with its Rocker + A.I. Core and NanoStar Solid Reactive Coverstock at a 2000-grit Abralon finish. It provides a controlled mid-lane read with a steady, arcing backend motion, making it a versatile option for various playing styles. Compared to sharper-reacting balls like the Storm Phaze II, the Rockstar delivers a more predictable, rounded motion, making it ideal for handling lane transitions. Bowlers praise its consistency and dependability, making it a great go-to option for those seeking control without sacrificing power. Whether for league or tournament play, the Rockstar is a solid addition to any arsenal. Will Tefft Roto Grip Pro Shop Staff Member will@parklanes.net www.rotogrip.com #SquadRG

To me, the RockStar had big shoes to fill. It comes in on the heels of the Optimum Idol being discontinued, and I had high expectations. So far, this ball has really stood up to those expectations. While it's not an exact replacement for the Optimum Idol, it fills a similar spot in the bag and provides a great compliment to the Phaze 2 and the Summit Ascent. The Phaze 2 is stronger on the back part of the lane, while the RockStar is earlier and more rounded. Both are stronger than the Summit Ascent, thought the RockStar has a very similar, almost tumbly shape like the Ascent. These 3 really cover all your bases, and if you're missing that early, predictable symmetrical pice or you've worn out your Optimum Idol and need a comparable replacement, this is the ball you're looking for! -Chase Valenzuela

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.
