Im thinking Im about half an inch too short, Ive been working on keeping my head straight and my string doesnt quit come to the tip of my nose like I would like. I havent had a chance to adjust it up an inch to see if thats significantly better but I'm curious if im worse case scenario and dead in the middle should I go longer or shorter?
I would agree with weekender but with that being said i do like mine alittle bit longer. Its all about you being comfortable.
Axle to axle length will also play a role in whether or not you can touch the string to your nose. A shorter axle to axle bow will have a much more acute angle to the string making it harder to get the string to your nose.
If I was off a half inch I would rather be short then long on hunting bow. There are a lot a variables bow to bow in so far as draw length. Some run longer then others, ata will play a roll and so will the types of stops the cam system employs. I have 4 bows right now and they are 50/50 between 28 and 28.5.
