I just redrilled two balls to use without inserts for the first time. WOW, so far after 20+ games I love it. Dont know why I didnt try this sooner.
I have a lot of "natural lift" ,as quoted by a couple of coaches, and when I needed to crank it up a bit more the fingers would swell a little. I would sometimes even get a split on the inside edge just below the first joint. No matter what ball I used or who drilled it. Pitches were confirmed by two different drillers to be correct. I burn through inserts so quickly, not even the ones with pitches just ovals, that I finally decided to give it a try.
So far no noticeable stress on the fingers whatsoever. Even if I push the rev's past 400. The feeling is good every time and I dont seem to have to fuss with my fingers as they go into the ball.
Maybe not for everyone, expecially the rev challenged like my wife, but I like it a lot and look forward to the savings on inserts and new skin. Only problem now is that I hang up in the ones with inserts. Guess summer is the best time for the change as I wont be needing all of them right away
