This sounds almost exactly like what I do
ORIGINAL: GMMAT
I may be all wrong, here.....but I don't think of it as "gripping" my bow. I'm allowing the bow grip to rest agaisnt the right spot on the inner part of my palm......the extension of my thumb(if you will). My fingers only rest on the front of the riser...because that's where they are most comfortable....and it assures me of no tension in my bow hand.
The "force" of holding the bow is applied by the fact that I'm at full draw. I don't "grip" my bow.
I hope this makes sense....and if not...I'm gonna learn something
