Roto Grip RockStar Bowling Ball

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!

LANE CONDITION Length:43 Volume: Med-High Type (THS, Sport Pattern etc):THS COMMENTS Core Rocker + A.I. Core Technology Coverstock NanoStar Solid Finish 2000 RG 2.48 (15) Differential 0.050 (15) 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 Under Ring 4 1/8 Pin To Pap 3 3/4 Pin Buffer There’s a new ball available in the HP3 line from Roto Grip. A new core and cover combo that gives this line what it’s been missing while keeping what it’s done right. The nano star cover continues the ultra reliable mid-lane read that was exemplified by the idol line but along with the new Rocker core adds down-lane motion and continuation. The result is a ball that will see the right part of the lane, the right way, on a variety of conditions. I tested the Rock Star for the first time in league on our fresh house condition. I was relieved to see the familiar roll that I rely on the combat the length of our house pattern and was a little shocked at how much the ball hooked off the spot. Too often I’m sacrificing one for the other so my speed and angles have to be more precise. I made an adjustment right and picked the speed up to keep it right of the head pin. I was slower than I like to admit figuring out that I didn’t have to try to stay as far right as I was. I paid the penalty a couple times for relaxing the ball speed. When the transition forced me left anyway I realized this ball was going the continue much better than I expected and I could have made the move left sooner. By the end of game three I stopped looking for the time when I needed to get out of the ball and into something shinier. I really didn’t even have to trick it any more than I do the stronger pearls in that part of the lane, this ball just keeps coming down-lane. I came back a couple days later to shoot a reaction video and picked up right where I had left off in league. I caught the lane after a league had bowled and put a couple more games on it while recording shots. Didn’t have to loft the front of the lane like I sometimes do, or try to muscle it right to get the speed up. It was one of the quickest vids I’ve ever shot. This ball is gonna be a hot seller for the pro shops, it’s got that easy to match up to motion that you get from Zens and phase IIs.

Introducing Roto Grips newest addition to the HP3 line, the Rock Star! This ball is featured with a brand new symmetrical Rocker core and Nanostar solid coverstock to bring more control, more versatility, and more continuation through the pins. Low RG, high differential provides this new benchmark ball to give more strength on a variety of patterns from medium to heavy conditions. Layout: 70 x 5 3/8 x 40, 2000 abralon surface. I tested the Rockstar at my home center at Cortlandt Lanes in Cortlandt Manor, NY. Bowling on a fresh 43ft league pattern, the Rock Star didn’t disappoint. I saw similar ball motion in comparison to both my Optimum Idol and Summit Ascent (both drilled with the same layout as the Rock Star). The ball motion gave more length, stronger mid lane read, and real smooth down lane. If I had to put these three symmetrical solid balls in order, I would have the Optimum Idol first, Rockstar second, and Summit Ascent third. The Idol is a little bit stronger downlane, as it can clear a few extra boards on the fresh. Proceeding to the transition, the Rock Star can then create more shape, more control and more backend across the boards. The Summit Ascent was a little smoother, but weaker with the downlane motion. I would recommend the Rock Star as an upgrade to the Optimum Idol in the HP3 line. The Rock Star would benefit those bowling on medium-heavy lane conditions pending surface adjustments. Be sure to stop by your local pro shop today and drill one up. Party like a Rock Star! Thomas Coco Storm Staffer

Roto Grip Rockstar Pattern: 41 Ft house shot Layout: 55 x 4 x 35 Surface: Box (2000 grit) The new Roto Grip Rockstar is a great symmetrical piece to add to the bag. The Rockstar features the new Rocker weight block combined with the signature A.I. core which allows players the option to play up the boards or swing the lane based on how they have it drilled. The new NanoStar Cover allows this ball to fit right in between the previous MicroTrax and ETrax covers by not being too early or too responsive. The versatility of this ball is unique for sure. When throwing it on the 41 ft house shot, I was able to play straighter up the boards and open up the lane when needed. The recovery on this ball allows it to be very forgiving as well. Overall, bowlers of all styles should be able to add the Rockstar to the bag and score with it. Trevor Kopas Storm Staff Ambassador Pro Shop Operator #Bigboybowling

With the unique design of the NanoStar Solid Reactive coverstock combined with the Rocker + A.I. Core, the Rockstar was built for medium to heavy oil conditions, and with its design, Roto Grip has a #1 hit on its hands. So, let's take a closer look at what makes the Rockstar so good for a straighter player like me! Let's look at the newly designed Rocker + A.I. Core in two parts: the Rocker Core and the added A.I. Core technology. I found the Rocker has a smooth motion in the mid-lane. I like how the weight block on the bottom brings a crisp and decisive turn when the Rockstar finds friction—further, being a straighter player, I liked how the Rocker Core is smooth and predictable in its motion. When you add the A.I. Core technology around the Rocker, you get an explosive, strong-rolling core that delivers pin-crushing results for straighter players like me. I like the potent impact the Rockstar had at the pins, and the continuation kicked out those single pins straighter players tend to leave because of our lack of rev rate. So, overall, I found the Rocker + A.I. Core delivered! Simply saying that the NanoStar Solid Reactive coverstock loves oil would not do its results justice. The NanoStar Solid Reactive cover has a strong bite as it cuts through the front part of the lane. Yet, when the Rockstar finds the pines or the middle of the lane, the NanoStar Solid coverstock was silky smooth and provided a predictable transition from the hook to the roll phase. Although the NanoStar Solid is designed like a snow tire in winter, I found the NanoStar Solid to blend from the wet to the dry part of the lane without being over-sensitive to friction. I like how it provided a stable, continuous motion I could count on. However, the one caveat I would like to add for straighter players is that the Rockstar needs to be in oil or along the shim line to see its best results. Otherwise, with my low rev rate on worn conditions, the Rockstar tended to roll out or run out of gas, not because of its design but because of my more down and in-bowling style. So, I suggest adjusting the Rockstar's surface to fit your game and the conditions you want to use it in, as I found the Rockstar adapts well to surface changes. In closing, Roto Grip has done a great job designing the all-new Rockstar! The combination of NanoStar Solid reactive coverstock and the Rocker +A.I. Core makes the Rockstar a great new addition to any straighter players' arsenal looking for that medium to heavy oil ball. So, stop into your local Storm VIP Pro shop today and have your Rockstar ready to roll because the Rockstar will keep your game rockin'!

Videos: Rock Star vs Equinox: https://www.youtube.com/shorts/vrc2OOtHcyU Rock Star 300: https://www.youtube.com/shorts/ywWEMy6nwbY What We Like: Equinox: https://www.youtube.com/shorts/ywWEMy6nwbY Rock Star: https://www.youtube.com/shorts/DURhoRMJJNM Reviews: Rock Star: Controllable and predictability are the main features of the Rock Star. Cleaner than an Optimum Idol yet smoother than a Phaze 2 this ball fits perfectly between these 2 popular releases. If you like to play your angles closed and closer to the right (for righties) this ball will be a great option to have. I mainly will be using this for sport conditions of shorter to medium ranges; however, I found success (including 300) with this on house conditions that play tighter and have more oil. This ball will take well to surface adjustments as well, if you need it to pick up sooner or later. Its versatility will allow adaptability to what the lane conditions are providing you. These benchmark type of balls are a must have for the competitive bowler. Equinox: This is close to a VEBO replacement although a tad smoother. If you like clean and angular motions the Equinox will be a great ball to have. Marketed as designed for most house conditions this ball will be able to be utilized on fresh and transition. I scuffed mine to 3000 to smooth out the backend and make it more usable on the fresh without being too angular. I have found for those conditions where the lanes hook early and play tighter on the backend this ball is a great option to go to as it will clear the front yet be strong enough in the mid's to allow it to give you continuation through the pins.
