Ahhh! The bent bow arm. A little bird told me that was probably what was behind the form thing. One of my pet peeves.

I' ve seen guys that bend their arms into an ' L' and almost rest their elbow on their hip when they shoot. I prefer just a very slight hint of a bend in my bow arm, about the same I have when shooting a longbow. I tell them their form sucks, they say the same about my form. As long as your elbow isn' t locked out at full draw, your string' s not raking hide off the inside of your forearm and your arrows are consistently hitting where you aim them, then whatever is comfortable is the proper amount of bend FOR YOU.

If you were holding your bow arm shoulder high, then it sounds like your form was pretty caved in. Dropping the shoulder low (as it definitely should be) should INCREASE your draw length slightly and let you hold more draw weight and resist creeping. It doesn' t make you any stronger, per se, but good mechanics lets you use your strength to your greatest advantage.

Head tilt... Could have been your peep was too high?

Just going on a semi-educated wild@$$ guess It sounds to me like you' re anchoring too far forward to keep your back muscles involved in the shot. I' d try going back to 30" and just seeing what it does for you.
