I would like to see a thread dedicated to this. I think it would generate some good discussion.
pros do stop the arm they are not pulling it till it hits the back fence
IMO the elbow should never get behind the shoulder line, try to pull it more against "the front of the side of the body"
and also keep your hand slightly in front of the back shoulder.
