Additional product information:

Ordinary? Far from it. Revolutionary? Absofrigginlutely right it is. Not only are we presenting you with the most advanced core technology since the invention of sliced bread, but we also decided what the heck, why not just mix in an inner block design never before released domestically. Yeah, you read that correctly, prior to this out of this world concoction from our R&D lab, the original Momentous™ Core was exclusive to our international market. But after countless seconds, minutes, hours, days and weeks of computer research and testing, we figured out that density changes to this particular block and slug when placed in A.I. Core technology provided us with a motion we hadn’t seen before. And after multiple on lane tests, it was a quick and easy decision that we just had to wrap this baby with the time tested and proven eTrax™ PLUS Pearl Reactive coverstock to give us an overall reaction unlike anything offered on earth today.

    Wow It Has My Attention

    Posted by Thomas Szczepaniak on Feb 27th 2024

    So I had no plans to drill this ball up but because it has the AI Core Technology it caught my Attention. I watched Mike SInek throw it at league the one night and it looked amazing. The following week I drilled mine up and it is now in my bag weekly. The pictures of the ball online does not do it justice with how amazing it looks in person. For me it gets downlane smooth like the IQ Tour Ruby but with the backend like the VEBO has. Now I see a lot more people with this ball and it definitely fits many styles.

    Attention Star Review

    Posted by Adam Chase on Feb 26th 2024

    Layout: 5 x 4 x 4 1/2 (50 x 5 x 70) Surface: Reacta Gloss The Attention Star brings the new Momentous Core (originally found overseas) with AI Technology paired with the etrax Plus Pearl Coverstock originally found on the RST X2. The Attention Star brings a more unique to the Roto Grip Line Up by being an asymmetrical pearl with less differential than the other current HP4 balls. The AI Core technology brings the RG down to 2.48 which allows this ball to read the midlane pretty well. I got to test this on a 44ft THS and a 42ft Sport Pattern. What I found on the house pattern, was that the surface of the ball is a little too clean to use mostly on the fresh but the core is strong enough to slow down in the right part of the lane. Removing the Reacta Gloss or giving a strong drilling can get the ball to be better on fresh oil conditions. The way I have mine drilled, I prefer to use it as a first transition ball due to the angle it creates. I have been very happy with this ball so far. It has much more versatility then originally expected and it reads the body of the lane very well. I had a 300 game with the first time using the ball in my league in game 2 which doesn't happen often. My pin down layout gives me slightly smoother motion then one would get with a pin up layout which I think enhances my ball reaction more. It doesn't seem to want to over flip in the dry much at all but can read the inside oil better than most other pearl balls in the lineup. On the 42ft sport condition, I see a lot of similar characteristics to the house pattern. The Reacta Gloss does not allow the ball to be fantastic on the fresh and it's not really designed for that. A ball like the Optimum Idol, Gem or Magic Gem would be a better choice for fresher oil conditions. After urethane and solid balls were used on the fresh, the Attention Star became the go to ball. It allowed me to open the lane up really well and I didn't have a fear of the ball not recovering down lane. Its strong midlane read gave me similar shape to a gem while giving much more angle down lane for continued carry. If you are looking for a medium strong ball to create angle down lane, then this Attention Star is a must to get. It has a lot of versatility and has been working well for many styles.

    Attention Star

    Posted by William Tefft on Feb 26th 2024

    Attention Star Cover Stock: eTrax Pearl Reactive Finish: Reacta Gloss Core: Momentous AV + A.I. Core Color: Berry/Silver/Iron Review: Still looking for a replacement for your UFO Alert? Look no further than the Attention Star. The Attention Star is another ball featuring the new AI core technology. I tend to pull this ball out of my bag when the lanes are just starting to transition. When throwing this ball you will see that it is great at storing energy as it clears the fronts and makes a strong motion on the backend of the lane. If you are looking for a strong asymmetrical ball to fit in right behind your Harsh Reality look no further. Will Tefft Roto Grip Pro Shop Staff Member #SquadRG

    Attention Star

    Posted by Chase Valenzuela on Feb 22nd 2024

    Attention Star is the return of eTrax+ Pearl, which was featured most recently on the RST-X2. This ball for me feels like a bigger version of the Rubicon UC2. Uniquely, it revs up and continues like a lot of the other A.I. core balls. What I loved about the UC2 is the way it picked up the in midlane but didn't overrespond off the spot. The Attention Star builds on that and provides a similar type of motion but in a stronger package overall. If you miss the length and predictability provided by the Rubicon UC2 and RST-X2, the Attention Star is the 2.0 version of that type of shape, with all the latest and greatest in core tech that Storm has to offer!

    Star is born!

    Posted by Tony Marino on Feb 19th 2024

    Attention Star Cover: eTrax+ Pearl Reactive Core: Momentous AV+AI RG: 2.48 RG Diff: 0.052 Int Diff: 0.017 My layout: 5 x 4.5 x 2.5 The Attention Star is a Pearl Asymmetrical ball that I see working best on medium to med-dry conditions. The pearl eTrax+ cover on the Star is clean but still maintains traction compared to other clean pearl covers. It does a great job of getting through early friction without being hyper sensitive to oil down lane. The strong low rg asymm core compliments the clean cover by revving up and giving the Star a strong medium to medium-quick response motion. I have found that the Star is best when the lanes transition past big solid balls like the Magic Gem or Reality. The Attention Star seems like a unique shape that will always be in my tournament bag. Gives me a lot of UFO Alert and RST X2 vibes!!!! <3 Bowler stats: Left handed PAP: 5 x 1/4up Rev rate: 400

    Roto Grip Attention Star – WWRD 2/16/2024

    Posted by Patrick Dombrowski (Storm Staff) on Feb 18th 2024

    Roto Grip Attention Star – WWRD 2/16/2024 Cover: eTrax Plus Pearl Reactive Core: Momentous AV + A.I. Core RG: 2.48 RG. Diff.: 0.049 Finish: Reacta Gloss Roto Grip’s new Attention Star is an Asymmetrical Pearl piece that is good for Medium-Heavy Volume Patterns. PAP is 5 5/16 R 1 3/16 Up. Rev Rate: 400. Speed: 16.5. Drilled this piece with the Pin above the bridge, CG kicked out 1” from the palm. I threw this piece on a fresh house 43’ pattern. Out of box ball motion was clean through the fronts with a hockey stick motion on the backend. I compared this piece to the Roto Grip TNT Infused and the Infused was 2-2 right with a smoother shape on the backend. This piece is similar to the RST X-2. If your looking for a strong pearl piece with backend this is the ball to get. Check Out the Ball motion Video on my YouTube Page:

    Attention Star

    Posted by Michael Slatky on Feb 18th 2024

    Roto Grip Attention Star Coverstock: eTrax + Pearl Reactive Finish: Reacta Gloss Core: Momentous AV + A.I. (14 pd) RG: 2.53 Differential: 0.046 Int Diff: 0.014 Layout: 5 1/2 x 4 1/2 x 3 1/4 - 2LS Layout Extras: 3 Finger Depth, "X" - 4 1/2 D and 1 Inch Left Tester: PAP 6 1/2 R, 1 1/4 D Review: The Attention Star features the Momentous Altered Variant + Amplified Inertia Core Technology. Basically what this means is Roto Grip has taken a core previously featured internationally and brought it to the states with a few upgrades. This ball pour is also quite stunning in its color combinations. The ball intent is to create a ball motion not readily seen in the SPI line of bowling balls. In comparison to my Roto Grip UC-2 and my RST X-2 which were 15pds the Attention Star may have more utility in my bag. At times my UC-2 would get a tad forward and my RST X-2 would feel a bit long sending it down the lane. To be fair the Attention Star does still seem unique compared to the balls I noted above. Especially in the middle part of the lane. The Attention Star gets length and I'm liking how strong it is and does not quit like other asyms I've seen in this category of ball. Maybe a better way to say this is that I'm liking the core and cover offering of this ball. For me, I really desire an option for sport and league patterns where control is the key, yet I want to have some asym options as a thumbless player. The Attention Star I did take some of the Reacta Gloss off with a 3K Abralon pad by hand. This helped me adjust the length of the ball, but did not have the ball burn up to soon on the THS HPL shots we bowl on. I feel the Attention Star is going to see a lot of play and has already been a PBA Tour favorite thus far. As noted the cover comes out with Reacta Gloss from the factory so I'm debating between that 3K and 2K Abralon finish by hand as I experiment more with this ball. I'm very excited about this particular ball being an asymmetric with A.I. and initial use has shown the ball has nice and strong reaction yet I do not need to get overly steep with angles. This is not what you generally see in most asym pieces. Be sure to grab an Attention Star today. It might just be the surprise of the season. Michael Slatky 900 Global Staff Member York, PA

    Attention Star!

    Posted by Josh Shoemaker on Feb 17th 2024

    The Attention Star is Roto Grips newest HP4 ball. The AS features the momentous core wrapped in eTrax pearl plus. Ever since the UFO Alert was discontinued, I’ve felt like the SPI line has been missing a similar shape. When I was first told about the AS, I had high hopes. Those hopes were exceeded and then some. For me, the AS is a clone of the UFO Alert. I was able to throw the AS right on top of my Alert. Having thrown the AS a lot already, I can see this one being in my bag for the foreseeable future.

    Roto Grip Attention Star Review

    Posted by Tobias Myers on Feb 16th 2024

    The Roto Grip Attention Star features the eTrax plus pearl cover and the Momentous AV + A.I. Core. This cover was featured on the RST X-2. This ball is clean through the fronts and plenty of shape down lane when it sees the friction. In the Roto line the Attention Star will sit below the Exotic Gem. I did compare it to the Exotic and the Exotic is just an overall stronger ball. It is earlier and will be able to handle more oil than the Attention Star. When the Exotic is too much ball, the Star will be a great ball down to handle the transition better. The Attention Star will be a great middle of the bag ball in the Roto lineup!

    Roto Grip Attention Star review by Lonnie Pemberton

    Posted by Lonnie Pemberton on Feb 16th 2024

    Ball: Cover: eTrax PLUS Pearl Reactive Core: Momentous AV + A.I. Core Finish: Reacta Gloss RG: 2.48 (15) Differential: 0.049 (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 Tall Over Ring 5 X 5 1/2 X 1 1/4 VLS The New Roto Grip HP4 release brings a core previously featured in overseas releases stateside, wrapped in AI technology. The Momentus AV + AI core is wrapped up with Etrax Plus Pearl to give you one of the most responsive pearls ever seen in the line. All together these add up to the new Attention Star. I tested the Attention Star for the first time in league. Our house shot while Longer and higher volume is very cliffed. On the fresh the cover tended to over-read the friction and under-read the oil as you would expect from a quick response ball on a 12 to 1 pattern. The attention star is much better for me game two when the fronts start to break down. Especially in my home center where the length and volume of the pattern tends to make the back-end tighten up a bit as well. Where this can give some balls fits, you can open up the angle with the Attention Star, let it see the friction to the right a little earlier and watch it tear through the carry-down. I do feel that this ball is a little pattern specific, at least with the layout I chose, but it's definitely a combination of clean and strong that you can tailor to different styles of bowler with the right layout.
