I tried shooting off the other side of the bow and promptly launched an arrow over my target, through the woods, without touching a thing, I might add, and very nearly hit my neighbor's truck. A deep hook works for me, but I'm not near accurate enough to try a shot at anything. On, my belly, yes. Last year, I shot a big ground hog after stalking up to him on my hands and knees. I nailed him while laying on my stomach.
I honestly don't recall ever, in 30 years of hunting, having to shoot something from my back. Not that it's not fun to shoot that way, but I just don't see the point in it, other than for novelty.
