Hi, for all you 210+, how is your thumb hole fitted? (I ask the higher avg bowlers because even when I'm pinching my thumb I can shot close to 200avg) So is the back of your thumb nail pretty much against the back of the ball? It seems impossible for me to get a comfortable fit with out squeezing on the back swing. Trying to use tape, tried inserts, tried smaller tighter hole (this was the worst, made my thumb swollen big time that I can't continue to use the ball)...I'm so frustrated now trying to fix this whole thumb issue. I'm more comfortable with a bigger thumb hole and squeezing, however I have reason to believe this is what's causing me to not be consistent. I also have a SMALL thumb if that helps for any info. HELP, I'm taking all advice...Thanks
