I use circle hooks for flatheads, Just let them load the rod up before touching it, then just pull back slowly, very good hook up ratio. Now I know you are supposed to set the hook using a J hook, I used to use them. But what would happen if you fished a J hook like a circle and just waited for the fish to load the rod up and hook itself? Would the fish swallow the hook? Or would the hook just not grab hold, resulting in a lost bait? Or would it hook the fish in the jaw like a circle hook does.
