I recently went from 0 pitch to 1/4 reverse (away) on my fingers. I also got rid of the grips and went back to plain holes. I was constantly cutting/splitting in my callouses where the edge of the grip meets the finger. Haven't had a problem since. At the same time I changed that I went back to my "old" pitch of 1/8 reverse on the thumb. I let an idiot talk me into 3/8 reverse and a slightly longer span a couple of years ago. After developing some forearm tendonitis, and the split finger callouses, I realized that something needed changing. Back to the past. John Ohanesian laid my grip out around 25 years ago, and he must have known what he was doing, because no matter what else I try, the "old" grip is still the best by far.
