Not at the lanes as am about to bowl. Am talking about during the week, so that on game day will have an easier time getting into the ball.

I DO have tape in the hole, that can be removed if necessary, but bowled so many games this past week, and thumb is so large, that I would like to reduce it faster in advance....if possible.

For example, I have used a corn/callus remover sometimes, but this is not just calluses. This is actual thumb size.

And I'd rather not have to open up the thumbholes on my equipment.

Won't be able to check back here till much later, but any feedback appreciated.
