I used grips for years, and started having the problems you described. So I experimented with one ball (a new one) drilled up with no grips. I found that I can get out of the ball much cleaner now, and am more accurate with my shots since I don't "hang up" like I did with the grips. Mind you, I didn't notice the "hang up" until I tried using a ball with grips after throwing the one without. Then I noticed it - big time. I cannot switch back and forth between grips and no-grips, so I now have everything without grips and am doing much better - especially on the spare shooting. I have not had any problems dropping the ball, and really, not much loss of revs. Wish I'd have taken them out years ago, actually.
