Roto Grips HP4 line gets another home run pearl ball, the Attention Star features a new core with Momentous AV + AI Tech and that is wrapped around the proven eTrax + Pearl. I drilled mine 5.5 x 5 x 5 and I’ve seen a few people throw this ball before I threw mine and was really excited about the motion. It is clean yet has a very defined forward motion in the back. This ball is more angular than the Storm Virtual Energy Blackout and doesn’t seem like much an stop it. Ive thrown it on a few patterns and it seems to roll good even when theres volume on the lane. It will defiantly be the second or third ball out of my bag on longer patterns once the front part of the lanes open up.
