On my recurve whether or not it has a deep grip or shallow grip, I grip them all with a high wrist, using only the thumb and 1st finger to hold lightly. It's more comfortable for me, puts wrist bones in-line with hand bones (more stable) and lengthens my draw length slightly, too, but this will add a pound or so of wt to what you hold. My palm doesn't touch the bow, so there's no torquing the handle. Practice serveral different ways and see what is more consistent for you. Everyone's anatomy is slightly different, and most bow handles are, too.
