I shoot a 64" "D" shaped longbow, a Border "Griffon GL." I think that is the best overall longbow length for treestands, ground hunting, and even many if not all blinds. I could go shorter but then you'd be pushing the handle forward, starting to reflex the limbs back a tad, in fewer words, shooting a hybrid. Not that there is anything wrong with that-I really want to get a Shawnee, but when I want to hunt with all the romance of a longbow, well, I think you already get what I am saying.
