With Open sites I have to shoot right handed Vs Left handed. I discovered when learning to shoot a bow I'm a lefty that is right eye dominate. I have never been able to shoot open sites with a rifle or pistol worth a crap,but was a excellent shot with a scope. I've started practicing with a right handed long bow and can shoot it much better than I ever shot a left handed bow.
