Roto Grip continues to amaze. This ball performs like a high performance ball at a lower price point. It is quite a bit stronger than the Dark Star, and still has the great hitting power. I found that this ball can be used on a wide variety of lane conditions with high success. To see the ball reaction, please go to the link below.
