Roto Grip Rock Star Bowling Ball

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 Keith C

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!

For me, the Rockstar is the ball that I was missing in the bag! A good fit between a big Asym and Phaze 2. Smooth and controllable down lane with a nice arc motion!

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.

Orientation: Right Handed Rev Rate: 400 RPM Speed: 16-17 MPH PAP: 4 ½ over and 1 1/8 up Location: Enterprise Park Lanes, Springfield MO Pattern: High Volume THS VLS Layout: Layout 1: 4 5/8 x 4 x 2 ½ (Pin above bridge) Layout 2: 4 ¼ x 4 x 4 (pin below bridge) The Rockstar is a new symmetrical solid HP3 Roto Grip ball. WOW! This ball is a lot easier through the heads than I thought it would be, but it still picks up pretty early! Compared to the Optimum Idol, the Rockstar doesn’t try to change directions as much off the friction and is a little slower, but still continuous. Overall I have the Rockstar pretty similar to the Optimum Idol, just a little cleaner/slower. I will throw the Rockstar a lot. It’s very usable and is a little cleaner than some of the recent releases.

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. With the new Nanostar coverstock 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

Another great heavy oil lane ball. Matches well with the Attention Star 2. If the Attention Star 2 goes just a little to long. Then the Rockstar will fill that gap. Same sweeping motion just a little earlier. Reminds me of the old Idol..

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 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!

With Roto Grip’s discontinuing the Optimum Idol from the HP3 line, we were left wondering what the replacement would be. Look no farther than the ROCK STAR! The Rock Star features the all new Rocker AI Core and NanoStar Solid cover. I decided to drill mine 4.5 x 4 and after throwing this ball for awhile and watching others throw it, I know this is going to be a huge hit. It has the similar overall strength as the Optimum Idol and Phase 2 but has a little more shape down lane than those balls. The Optimum Idol is my favorite ball in my bag and goes with me to every tournament and I find that the Rock Star is the perfect ball down for me from it and is more of a benchmark ball in the line. If you are looking a benchmark ball with a little more shape down lane than a Phaze 2 or just a replacement for the Optimum Idol, pick up the Rock Star today and get your rock on !

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!
