The first night in my HH was miserable, little sleep, backache etc. I was so disappointed. It was still hanging and I tried it again the next night, trying to figure out the diagonal thing etc. The first night I tried zipper right. While experimenting the second night I tried zipper left, WOW, totally different hammock, comfy, I slept. I have spent at least 15 nights in it and consider myself a complete newb, still experimenting. Example: I snapped a little line level on the ridge line to keep a fixed reference point on at least one variable. I found I do better with it showing the ridge line a little high towards the head end. Man, there is a lot to experiment with!
