My wife and I are both side sleepers and on our last hike found the tent route very uncomfortable. I did't sleep more than an hour or so each night on the trail. We just bought the ENO Single nest and Pro Fly tarps and will be trying them on the AT this week. We did go out to the woods and test out the set up and laid around in them awhile.
Did a short video.... check it out http://www.youtube.com/watch?v=zeA963f8iuU
