I think I prefer keeping my left shoulder tucked in and having bend in my bow arm. I'm going to try sticking with 29" and push my bow arm out just enough to keep the string about at the corner of my mouth and see how I shoot so my draw arm isn't torquing around unnaturally. Pushing my bow arm out most of the way as in the last picture seems unnatural. I was still able to keep my left shoulder tight in post #25.
Might have to put a kisser button on to make this new positioning habit.
