I have the HH backpacker asym and spent my first night in it last week. I use (at the moment) a CCF pad and Ray Way quilt. My feet and head seem to naturally go asym across the centerline and it does flatten almost like magic - I slept on my side most of the time and I toss and turn. It didn't feel like a hammock, and no problems with the butt dragging; I was only a foot and a half off the ground, as I didn't trust my knots and didn't want to fall further than that <img src="/forums/images/graemlins/crazy.gif" alt="" /> but had no issues at all with falling or being curved into a banana.

The trick to the HH is to get the foot end hung higher than the head end - this seems wrong, but it works. I woke at one point curled into a fetal position over the slit because I had slooooowly slid down. I thought I'd fastened the foot end higher, but I guess it needed to be higher still. But it was nothing to straighten out and readjust. The hammock is SO much better on my hips and knees than the tent. I got up the next morning feeling none of the stiffness I would have felt had I slept on the ground.
