I think it really depends on the shooter, Ray. Many folks do better with a target-style grip... putting just the web of the hand into the bow with fingers extended away from the riser, or some variation. I know some excellent shots that shoot hunting bows that way but in my case it doesn't work well...I need to control the bow more. A firm palm grip is especially helpful when the shot angle, bow angle and 'situational difficulty' (leaning over in a tree or under a branch, etc.) are less perfect than a standard straight-on and straight up 3-D type shot. Add a loaded bow quiver (weight to one side of the bow) and holding the bow as opposed to balancing it on the web of the hand makes sense to me...and it's proven more effective for hunting, in my experience. That's the bottom line.
Years back, when I shot recurves with more of a web hold, I had alot of problems with the string hitting my arm. Another double benefit of the palm grip has been that except in very cold weather when heavy clothes are needed I don't even need to wear an armguard anymore, and the bow shoots quieter as well (the hand/arm acts more like a stabilizer). As long as the string is pre-tensioned to get good alignment from grip through the draw hand, and the release is clean, I've had zero problems with bow torque.
Whatever works for the individual, thats what makes the most sense. Still. it's fun to see how others do their thing.
