Question
I HAVE A PROBLEM WITH MY THUMB GETTING BIGGER WHILE I BOWL MY THUMB FITS REALLY TIGHT SHOULD I MAKE IT BIGGER AN USE TAPE I USE A THUMB GRIP BEFORE I BOWL TO MAKE MY THUMB SMALLER THIS GIVES ME A GOOD FIT ON MY THUMB BUT IT DOES NOT LAST CAN YOU HELP I TRYED GOING UP ONE SIZE UP THEN IT IS TO BIG I USE A OVEL GRIP WOULD A ROUND ONE HELP

Answer
I would suggest opening the thumb hole enough to be able to start with a couple of pieces of tape.  As your thumb swells, you can just remove the tape.
Another option is to have a switchable thumb installed.  You could them have thumbholes of different sizes to use.  The tape will be the cheaper option.

Good luck,
