I think that hammocks are very comfortable. I want them to work. But, after I add in tree straps & a big enough tarp, I'm packing in as much weight as a tent but exposed to skeeters all night and still leaving a lot of my gear exposed to the elements. It's a nice idea. I just can't seem to make it work better than other, more simple options. The fact that I can sleep anywhere doesn't help. I figure that if I'm packing in 3# of "shelter," I may as well get a bug screen, lots of room for my gear & enough room to comfortably shift around as I read at night.
If you're only going a mile or two, then take the kitchen sink. I've gone back for second loads when the distances are short. I've even carried 2 packs at once. But if you're packing in more than just a few miles, you're going to want to cut weight and space. After all, if you end up getting something, that has to come out, too.
