I injured my right hand (snipped a finger tip off in a tractor fan - now reattached) a month ago and have had to switch to lefty. Boy, does it make you concentrate on form. I bought a 41# LH bow (a Red Wing Hunter) that I draw to about 45#. At 15 yards I am shooting a dozen shafts daily and trying to get so it feels narural. So far it does not. But it is improving. The draw weight has not been a problem; but the focus and anchor sure has!
The "rotational draw" mentioned hereabouts is what previously we had called "full draw". I'm 6'3" and pull a full 30" and have a relatively upright, target stance as that was where I got my start (single-pin 18 & 25M target archery in college).
I have been working on one thing at a time: bow arm, draw elbow, anchor, release (I do mostly static), stance, etc., etc. It has been an excellent exercise.
