Experience the extraordinary with the Roto Grip Attention Star bowling ball. Unleashing groundbreaking core technology, this ball introduces the exclusive Momentous Core domestically, paired with an inner block design for unparalleled ball motion. Roto Grip's meticulous research led them to discover the perfect combination of block and slug density inside the A.I. Core, propelling energy dispersion through the pins to another level. The eTrax PLUS Pearl Reactive coverstock, identical to the successful RST X-2 formula, offers optimal front-lane push and impressive responsiveness to down-lane friction. This bowling ball redefines the game, delivering a reaction unlike anything else on Earth today.

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.

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.

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!

The Attention Star reminds me of the X2 from Roto Grip. We have a asymmetrical pearl with polish that is clean and provides plenty of shape down lane. This ball versatility fills a few spots for me. I can use this on the fresh where the fronts typically hook early and during transition when I look to open my angles up on the better lane surfaces and or higher volume patterns. If you enjoyed the X2 this would be a suitable replacement.

The new Attention Star from Roto Grip is one amazing addition to the HP4 line. The Attention Star provides effortless length through the fronts, and a great move off the end of the pattern. I really find this piece useful when the fronts start to go, but there is still lots of hook off the end of the pattern. The Attention Star slows down in the right spot, allowing it to not overact as soon as it sees dry. It is an excellent piece to go to, between a stronger asymmetric/symmetric ball like the Harsh Reality or Optimum Idol, and before a VEBO or IQ Tour Ruby. Own It today!!

The new Roto Grip Attention Star! Features the Momentous AV + A.I. Core with the eTrax plus pearl cover wrapped around it. With the A.I. Core you still get good continuation and powerful light pocket hits.  Liked that the core numbers were a little lower than a usual asym ball and a weaker yet proven cover. The Etrax Plus Pearl was on the RST X2 and that ball was quite usable. Glad to see they decided to bring this ball stateside.
This ball to me is a little stronger/earlier than the Storm Virtual Energy Blackout and a little more forward. I immediately hit this with a 2000 abralon pad to remove the shine. What shocked me is the Star did not feel whippy or uncontrollable even on fresh. I can see why the pro staff is using this ball out on tour a lot. The ball is easy through the fronts, mid-lanes strongly, and has a controllable pop on the back end. This ball will be good for many conditions especially in the Pittsburgh area where we see a lot of hook in the fronts.
This ball will be great for a variety of styles. Whether you a just a league bowler or you are a tournament bowler. The strength and controllable pop will help many people score well. You will want to check this ball out. Roto Grip got our attention with this star!

Roto Grip Attention Star

Ball specs: MOMENTOUS™ AV + A.I. CORE TECHNOLOGY with E-Trax Pearl coverstock and finished with Reacta Gloss finish.

Layout: 5 x 3 ¾ x 3

Bowler specs: 15.5 mph and rev rate in the 380’s and my is PAP is 3 ¼ and at zero up/down and tested on Pro-Lane at ABC North Lanes in Harrisburg, Pa.

With the introduction of the Momentous AV core that has been used overseas in the Roto Grip Attention line since 2020, it was awesome to see the minds at Roto Grip bring that core to the World-Wide market.  Wrapping the core is the all new A.I. outer core technology that was introduced last summer at International Bowl Expo, it is given the tour players a “cleaner” reading ball that the line has been missing. For us, the average Joe Bowler, that equates to a ball that stays true in reaction and is able to be used across a broad range of house patterns and tournament play. For me, the Attention Star is the FIRST ball since the start of the fall bowling season that I have been able to use through the whole league matches. May it be a 2 person / 4 game scratch doubles, 3-person scratch league or a 4-person mixed league, I am able to stay in the ball all night long and the overall reaction in the back end is weaker than the new Storm DNA Coil, but stronger than the Magic Gem or the Absolute Power. I would say it's very similar to the Storm Virtual Energy Blackout, but just a “tick” smoother on the dry friction. I mainly used it on Pro-Lane at ABC North, but had the pleasure of using it a Colony Park Lanes in York, Pa., where the surface is older HPL with a TON of fraction, every other ball I tried, jumped real strongly off the back of the pattern, but the Attention Star plowed through and was able to bowl a very respectable match (for myself) 963 for 4 games. 

The Attention Star is #3 in out of 4 in ball strength for me and will be replacing the VEBO. In order of strength will be #1 – DNA Coil, #2 - Optimum Idol, #3 - Attention Star and #4 – Hustle RIP. For Colony Park Lanes my bag looks a little different: #1 – Optimum Idol, #2 – Absolute Power, #3 – Absolute Power and #4 – Lighting Storm or Ocean Blue Ice Storm.
