Ok fellas, I'm trying to establish my draw length and my wing span is 75 inches divided by 2.5=30 inches. Pretty easy right? Ok well where I get confused is with the other option which is by height. I'm 5'9 3/4 and it says my draw length should be between 27.5-28 inches. That's 2 inches. Big difference in draw length. Which should I go with?
