As far as shorter bows, he might try the Predator by Pittsley (Hunter's Niche) in 62". I draw 32.5" and it does not stack at all. I could draw more with that bow... if my arms were longer! Very smooth and one of the fastest tested by Blacky Schwartz. They are reasonably priced too. My Black Widow PTFX (62") does pretty well with my long draw also. Ideally, a 64" bow would provide a smoother release due to the string angle, but I don't care for longer bows, although I may get one for 3D shoots some day.
