I don't got too much to add, but I think a bulbous handle can feel just so right sometimes, somethin to really fill up your hand. Also, I think (THINK, as in I have no real idea, but am just kinda guessin, so take that into account) but I think that stress of the bow hand should be more focused at the bottom or heel of the palm, the part you push the bow with. Verses the upper part near the thumb. I think it's better use the bow hand to just hold the bow in place mostly with the pinky ring and middle finger, and use the strength of the arm/shoulder/back, etc, to do the work of drawing the bow. When people shoot a Yumi, you can see the bow flip around after the arrow is shot, because they are holding bow the lightly in the hand, not giving it the grip of death. Holding the bow firmly with all my fingers wrapped around, clawing it for dear life I guess, feels unnatural to me. I have tried to shoot like that. But the best way for me, (especially for heavy bows) is to use mostly the bottom of my hand, pushing off with the bottom of my palm. I really don't know, but I thought I would share my thoughts.
