Last week I don't think I missed the pocket over twice, yet I kept leaving 4's, 8' and 10 pins.  I moved more inside and outside.  Then I changed to a less agressive ball.  Slowed down my speed some.  Nothing seemed to help.  Yesterday, at a different house, I had the same problem.  Started with an Arch Rival which was over hooking a little, then changed to a Cool Noize and was in the pocket almost every shot.  Shot a 570 that would have been well over 600 if I just carry better and don't miss a couple of 10 pins.

My question is what do you do when you have this kind of problem?
