Roto Grip X-Cell Bowling Ball Review

The Roto Grip X-Cell brings back the fan-favorite Nucleus core design from the original Cell with an upgrade to the AI outer core system.

As good as the ball was on the fresh, he was worried about it burning up as the pattern broke down. This worry was short-lived, though, as he had no trouble getting his ball to continue to split the 8 and 9 pins as he got deeper with his laydown point in transition. The box finish easily chewed through the oil in middle of the lane, providing tons of continuation and lots of hitting power. He preferred the motion and shape this ball provided over the Magic Gem on this condition, even though it covered fewer boards. The way the X-Cell went down the lane later in the session was also very impressive. Cranker didn’t change the surface at all on this condition, as he was able to simply move his laydown point farther left to find more oil in the front to keep
