i prefer straight, but not locked, shoulder down, but not everybody's body is built exactly the same and what works best for me may not for you. i anchor and that's it. from then on the only thing that moves is my hips until i experience release. what i mean is i acquire my aiming point with my hips. for me, where my hips are pointing, the arrow is going there regardless, so that's what i use to aim right and left and up and down. if i start off in the proper stance the only thing left after anchoring is up and down, and i do that by bending at the hips. when i stopped aiming with my bow arm my consistancy went to the next level along with my ability to hover on the dot.
