Okay, so I'm sure most of you are going to say "whatever's comfortable", but here's the situation. I'm planning to buy my son a Mission Craze for Christmas. It's quite adjustable, both draw length and weight. I can adjust it if I need to, but I want to have it setup pretty dang close to what he needs, so he can go out back and shoot it Christmas morning. The problem is, that I need to buy arrows, so I need to know what his draw weight is, or close to it. So for those of you that have a 12 or 13 year old shooting a bow, how much are they pulling back? I don't want to give him any clues that I'm getting him one, so I can't take him to the archery shop. Any help is much appreciated.
