I have a firm 30.5" + draw length and fairly large fingers. My go to buffalo is 64" and my go to thunder child is 56". I personally can't tell the difference between the two when I shoot them. Yes, with my drawlength, I would normally suggest 58", but what the heck. I know the boyer and he said I could shoot the 56". I like it and use it mostly in close quarters such as blinds, but could use it anywhere. If it was my only bow, I don't know that I would opt for the 58" or not.
