Description

After countless months of research and development, and after multiple tests and discussions with players of all skill levels, the Roto Grip ROCKSTAR provides a new motion and reaction for both the competitive player ranks and the advanced player ranks to shred and rock on those Medium to Heavy Oil Conditions. Offering new state-of-the-art technology in both the coverstock material and weight block shape design, the ROCKSTAR was developed to provide greater versatility on more oil conditions and lane surfaces than previous HP3 level balls since there have been plenty of advancements in the world of lane maintenance and lane surfaces in recent years. The new NanoStar coverstock material is our latest nanotechnology remix. This union of nano particles mixed with new chemistry provides similar traction in the midlane to that of our legendary MicroTrax material. However, the difference you will easily see is that the NanoStar material does not dig into the lane as early as MicroTrax, it generates more responsiveness to friction down lane in terms of nanotechnology materials. In other words, breaking it down a little more for you... NanoStar is not as early as MicroTrax, and it’s not as clean and responsive as our eTrax, eTrax PLUS, or eTrax ULTRA materials. Therefore, it fills the gap between MicroTrax and eTrax. Showcased at the center of it all you will find our newly developed weight block shape that is destined for greatness, known as the ROCKER Core. Its authentic shape encapsulated in A.I. Core technology provides a more centralized rotation plane to better provide more continuation through the pin deck. As always, our team of R&D rockstars aim to develop weight block shapes that perform for bowlers of all skill levels not just the ones you see on TV. Meaning, the ROCKER Core is no different, it was designed for the masses. Let’s just say, the combination of amplified power and amplified motion results in sheer amplified awesomeness. So, if you are indeed ready to rock, then look no further, ROCKSTAR is here and ready to make you famous!

I purchased this 14lb roto grip rockstar about 3 weeks ago and I love it. I have about 15-20 games rolled with it, Just had first league night of the year and rolled a 695, I have a 188 average. The rockstar does have smooth, predictable reaction and nice backend. If you are thinking of getting this ball, just go for it, thank me later ... show more
