Roto Grip RockStar Amped Bowling Ball

Whether you’re chasing scores or just want a reliable ball that matches your style, the Rock Star Amped delivers. It’s a versatile, confidence-building piece that helps you stay consistent and competitive on typical house conditions. If you're looking for a ball that blends control, power, and forgiveness, this one deserves serious consideration.

Amped is an understatement when it compares to this Rockstar. I loved the original Rockstar because it was one of few symmetrical solids I was able to move left with and still get it to finish strong. The Amped reacts the complete opposite for me on the fresh, that I have better results when I move left. This so far is one ball that is a touch too strong when I play straighter from the start. Now once the lanes transition and there is some carry down this ball is truly amazing. I used this ball this week for game 3 in league when the RST Hyperdrive Pearl started pushing a little too much and it was my saving grace.

Dual Angle: 55 x 4 1/2 x 25 Storm Vector: 4 1/2 x 4 1/2 x 1 3/4 I was super excited for the Rockstar Amped and it did not disappoint. I drilled this ball with my standard layout which the thought that it would be my step down pearl symmetrical ball. This ball is clean through the front with a nice predictable backend. I expected the ball to be really angular but was pleasantly surprised by how smooth it was on the backend. For me this ball is the Attention Star but a bit weaker. https://youtu.be/T3TSwapWzhA?si=FJSZgskM3bCYHAkY
