Hi there 'dough. I'm afraid that callouses are like fingerprints - everyone's got a different set. I've been playing for many years and have rarely ever had any fingertip pain. The callouses that I have built up are very light, and almost invisible. Best suggestion I ever heard was to soak 'em in salty water. That's what pitcher Al Leiter did, and it seemed to work for him.
Thanks Peter for being first to go in that direction, I'm relieved you got there before me.
