but i have also seen guys just stick there fingers out strait and lock them, and thats not good either
I hold my bow this way, but relax my fingers. It' s worked fine for me for over 18 years. I also shoot a high wrist. THis prevents me from kicking my arrows high with my palm. The bow rests in the web between my thumb and forefinger. I use a jersey glove to that my hand can slide into the proper position even if it' s sweaty.
One word of caution, if you use an open grip, get a wrist sling!!!
