Don't go too short!!
I own four Javaman bows and my shortest (56") is an Elkheart Double Carbon TD. The bow shoots lights-out, but I know for sure it is less forgiving for me than my 64" Falcon XL's that I shoot the most. Some of this may be because it is my heaviest bow, poundage wise, or perhaps because I shoot the others more?? This is all with a 30" draw, so results may vary for you. I always try to keep into perspective, is an inch on either end really going to make a difference when in a tree or blind?? If you can't answer with a definitive YES, go with a longer bow. My two-cents anyways.....
Best of luck, Gregg is a great guy and true craftsman!!
