This ball produces the strongest hook of any ball in my arsenal.I like the core/coverstock combination of the master. I could play a deep inside shot and really swing it out and this ball came back crushing the pocket. My drill pattern was a 50x5x40. I put a balance hole in the lower right part of the ball.known as the P3 position. I wanted to get as much length as I could but I didn't want to loose the hitting power. This ball would be a great add to anyone's bag and a must have for tournament players and sport shot bowlers.This ball did not let me down,I love it.
