Bowling adjustments
Well, seeing that my bowling ball was not working out for me, I had the thumb re-drilled. They re-measured it and found the grasp to be 1/4 inch off as well as the thumb hole needed to be drilled straighter than the angle that was on it. I haven’t tried the new fit out yet, but i am looking forward to it.
Cheers!

Great site. A lot of useful information here. I’m sending it to some friends!
I will let yo know if my bowling ball turns out to be fixed….
What a great resource!
