Finger grip tightness is strictly customer preference. Some like them tight, some loose. When I fit I select a grip that, if pushed, will go about 1/4" past the joint. Then I show the customer what one size larger and smaller feels like and go with their choice. I'd say more prefer looser than tighter. Personally, I prefer a loose finger fit, but I don't use grips. I like a hole that is large enough that I can push the finger almost half way to the second joint if I wanted to, but only put it in to the first joint. You only actually use the front of the hole anyway, sides and back don't make much difference. -- JohnP
