RE: Question Involving grip tightness.
I shoot with a " grip" just like that first picture, " angle hand" . I do not close my fingers, and I do not lower my palm down to the bow. I had a problem where I was kicking my arrows up from doing that. So, I just rest the bow in the web between my thumb and forefinger and shoot with a " high wrist" style. Has worked wonders for me for 18 years now.
