Roto Grip Rock Star
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 !
