"correct archery form" always has, and always will be,
the form that's most consistent for you, not me, and not anyone else.
with that said, if you truly have a 30" draw length that works yer deltoids, don't hunker down, lean forward into the bow, and shoot a 28" arrow - what, you think yer a howard hill???
:D
aim however ya like, but do consider and try "aiming the arrow" - it's a very positive alignment process/method. you don't directly look at the arrow, it's part is strictly to get your "gray bow sight" (brain) centered on the mark for left/right. then set the trajectory with yer bow hand.
