I' ll repeat myself in case you missed it.
Don' t blame confusion at the moment of truth on the equipment.
He' s not adpt to miss because he uses 3 or more pins but rather so by useing the wrong pin.
About as apt as he is useing 1. Both ways are only as good as ones abitility to estimate yardages. I' d rather have multiple pins in the kill zone,(leaning more to the one I estimated the yardage at), than one over the top of his back.
