I drilled mine 50deg x 3" x 25deg with a P3 weight hole and the ball is butter smooth! It's not a first ball out of the ball, not unless you're on short oil. I can play the friction area with this ball and it doesn't overreact. The cover is the answer and takes the wet/dry out and is very controllable. I love this ball for shooting spare as well, because it's predictable! Just my $.02, Bruce
