I'm 67" and I shoot a 68" longbow (the Vixen), 27" draw length. I think bow design plays a factor. I haven't heard of many people favor shorter ASL style bows, probably a reason. I have owned and shot 58" recurves, 60" R/D's, etc. Physics is physics. Short bows with a longer draw will crowd your fingers more or "pinch". Longer bows with a shorter draw will reduce the working area of the limbs and effect performance potential. As for "stability" thats pretty speculative I think. Bow design (woods, glass, mass, etc) can change a simple design drastically. So, lets put physics behind for now. I don't hunt from stands, but people do with 68"+ bows. Blinds is a different story. Blind size matters of course but I still wouldnt want to hunt in one with a 68" bow unless it was a very large blind. I use brush blinds and a stool and have never had any issue that would have been solved by less bow length. I will say this, the first few times you hold a "bow as tall as the shooter is" it will feel quite long. Over time it tends to shrink and the shorter bows feel like playthings. Different strokes for different folks and everyone has their preferences, but remember, if you ask a bunch of bowyers who build short bows which is better your going to hear why 1,000+ years of archery knowledge is suddenly wrong.
