I need at least a 66" bow (28"DL), but I want to be able to shoot ASA 3D and tbot.org stuff which requires shooting off the shelf. The 19" riser seems to be the only size for shooting off shelf. Long limbs and 19" riser will get me a 64" bow. I have a 60" one piece, but it is too short of a DL--by about and inch or so without stacking hard. Would a 64" be just enough to get me to full draw without stacking hard?
