Exactly 10 years ago back in 2000 I went to a power game at the time and was using grips. I kept on breaking the grips and learned from former and current pros on the tour along with other people that going to "finger tip drilled" without grips is a better way to go. Everyone on this board has been debating using grips vs not using them. I went to finger tip drilled and never looked back.
My game has been revolving around more power and even keeping a relaxed grip my fingers have been hurting for years. About 3 years ago I bought a No Mercy and decided to try and find a driller to help my painful finger problems. That was the start of my joints on my fingers getting big callouses and literally changing the shape of my finger especially on my ring finger which is red raw on both sides. Not only that, I can't curl/bend my fingers in my right hand very well like my left hand and know it's because of my grip.
Well back then the driller recommended that I go to 1/8 reverse on the fingers. Tried it and hated it. Kept coming out of the ball and kept dropping it on the foul line and could not produce much power on it. So after a month of that and stopped using it in leagues I had the same ball plugged and drilled back to the way I have all my balls. However, everyone knows using epoxy plugging can make the finger holes slippery after it is drilled into which is a downside.
Two nights ago my fingers were hurting bad I had to do something for my Friday league last night. I have 1 ball left with grips out of 10 in my closet. It's a Storm El Nino from 1998. Good condition and loved the ball but was so against grips I just stopped using it but never got rid of it or sold it. So I used it last night and....no pain! I also shot near 700 and every ball seemed to be consistent off my hand unlike my finger tipped drilled balls. The best part I have no pain from last night. I also believe I can get more revs with grips. I proved it by for fun bringing that El Nino with 5 other balls to practice and my El Nino outhooked everything I owned including a Gravity Shift by a mile.
So making the decision on getting grips into my balls and all future new balls. Hopefully someday my fingers will return to normal. If I was to do this can a driller just drill the holes into my existing finger tipped holes for the grips without having to plug the balls first? I know I have some older balls that has longer spans and wouldn't work without plugging it probably but if the ones I have with the same span can it work without plugging it?
