In order to accommodate the long draw, I needed to drop the right elbow and straighten the left elbow perfectly. I was putting a lot of stress on my left shoulder and sometimes I was pushing it up or towards the arrow because the left elbow was not strong enough in that straight position.
Also, the lowered right elbow was not allowing the right forearm and the arrow to be in the same plane, which affected the release and more importantly the instinctive shooting ability.
For target shooting at long range this method (very long draw) might work very well, but for fast shooting involving instinctive aiming, moving targets or horseback archery, I found that the shorter draw fits my needs better. The bow doesn't complain either.
Anyway, draw length should be chosen after all other variables are fixed: first choose your front end form, arrow level across the face, arrow to draw hand forearm angle, left wrist position (gripping style), right wrist position (I prefer and recommend a flat wrist), bow angle etc. Then, when all these are fixed, simply measure your draw length.
