I have the Expedition A-Sym. I'm 5'9" tall and I fit quite well along with all the other stuff I bring in the hammock with me. If I were 3 inches taller, I would opt for a larger hammock. I seem to fit perfectly on the diagonal, but I wouldn't if I was taller/longer. I would definately have a knee hyperextention problem.
NCPatrick - I'm curious about the complaint of not being able to reach out for gear. What gear do you need when in the HH at nite that you can't bring inside with you? I'm not picking on you specifically, I've seen this often as one of the primary arguments against a HH. I cook dinner before I get in the hammock so I don't have to reach out to work my stove. Everything else I could possibly need goes into the HH with me. Pad and bag, small stuff sack containing wallet, camera, first aid(basically just pills),pocket knife and other misc. junk that gets attached to the ridgeline loop at the head end. headlamp, tobacco, papers, lighter, ashtray(film cannister), and a couple unmentionables all go in the mesh pouch hanging from the ridgeline. I added my own zippered nylon pouch to the ridgeline that holds pen, journal, current section map and guidebook pages, book for pleasure reading, snacks and any trash I generate. I have a 20 oz. water bottle with a short lanyard that hooks onto the plastic hook Hennessy provides on the ridgeline. My radio clips to the ridge line above my head. My sleeping bags stuff sack gets tied to the ridgeline at the foot end empty or containing extra clothes if I think I will need them. And I still have plenty of space for other stuff. The only thing left in my pack are my hiking clothes, water bladder, and maps I'm not using. Everything else gets hung from a tree. I know a lot of top vs. bottom loading is all about personal preference. I just don't get the "not being able to reach out for gear" argument against the HH. What gear are you reaching for? I'm not trying to start a fight, just curious.
