mmm, i thought the rule is clear, where if the thumb hole isnt being used as a thumb hole, it is deemed a balance hole. If the ball had an existing balance hole this would make the ball illegal. I didnt think there was anything about covering the hole, the hole is still physically drilled in the ball. You would have to have a shorter span than normal to cover the thumb hole. I would need to take the thumb hole forward over half an inch.
