if your 6ft tall, good chance you will eventually draw more that 28", the anchor point is not necessarily the corner of your mouth like is often quoted. The upper portion of your draw arm should be in line with your chest, this allows your skeletal structure to hold some of the draw weight. Just keep your elbow turning the corner till the upper arm is inline, where your hand is at that point determines your anchor point. For instance, me an my wife have monkey arms, she's 5'8" and draws an honest 29", I'm 5'11" and pull 31", but like I said we are freaks and have really long arms and fairly wide shoulders. If you practice getting your arm back like I said when you draw, you will be able to hold longer and aim better theoretically, my wife is good at that, me, not so much!
