When starting to make bows I never shot bows previously.Fiberglass or compound.Made some with small glue on shelves but eventually for quite some time now have been shooting off my index finger knuckle and never went back to a shelf target shooting or hunting in a stand,blind,or even stalk type hunt.Shot dozens of deer with this set up.
I've shot friends bows with shelves and they shoot nice but prefer to shoot off my index finger knuckle.Handles are a big deal with self bows.My bulbous ones feel very comfortable for me.
