The arrow fit seems right. I've been anchoring with my knuckle behind my ear, nose on the string, fletching touches the edge of my mouth. I'm grouping three arrows in an inch (ruined some fletching) at 10 yards. I'm working on the bent arm thing, seems more natural, or at least easier, to hold full draw with a straight arm.
