Hello all, I'm new to the board and I'd like to say that this is one great resource for newer bowlers. I've only been bowling seriously for about 6 months now and I've learned a ton in the past few weeks, just from reading posts here.
Anyway on to the question. I just bought a new ball (Storm Double Agent) and it's definitely a switch from my Storm SpitFire because of the two types of coverstocks. So I have a fingertip grip drilled in both balls, and the spitfire was just redrilled because the shop that I bought the ball from drilled my ball 3/4 inch to short. So I had that ball redone and the guy I took it to did an excellent job. When I got my Double Agent it felt great the first 2-3 games that I bowled, but I noticed over the last 2 weeks that I'm starting to develop a callous on the side of the thumb.
I'm wondering since the same guy drilled both balls why one doesn't do it but the other does, and could this be a sign that I'm not gripping the ball correctly? So this is out there, he used the same dimensions on both balls.
Sorry for the long post
