Yeah, your best bet is to take it in and have them measure the new pitches with the
tape and everything in the hole.
That said, it is normal to tweak your ball-fit with
tape. If you sanded the hole out to make it bigger, changed the bevel, or really did affect the pitch, the driller can copy that when they drill future balls. However, you can expect to add and remove
tape to your thumbhole over time as your thumb shrinks and swells.
