I've never done well with stronger cover / big asymmetric bowling balls.  My release and speed isn't strong enough to get these balls down the lane, and still have energy at the pins. If anything they just move a few boards, roll forward too soon, and have no backend or recovery.  More oil means they hook less, and do less. More surface doesn't mean more hook, it usually just means rolling forward sooner and doing nothing. I have pretty low tilt.   Just wondering if there are specific layouts that might help get better reaction out of these type of balls?
