OK, well unfortunately my new
Pro Shop guru was swamped when I picked up my ball, so I wasn't able to pick his brain about what all was done. However, I can tell that he evened out the finger holes (I think one was further from the thumb than the other, before). The thumb hole was initially a little too snug but he ovalled it out slightly and...all I can say is, one piece of
tape to the front of the thumbhole, where the pad of my thumb touches, and it's like a whole new ball. Shot 50 pts higher tonight than I've been doing.
I think my wife is having the same thumb problem I was having, so her ball is next to go to the guru. (BTW, if anybody is from the Vancouver, Washington area, the guru is Dennis at Bailey's Classic Lanes...I hope it's OK for me to say that.)
