Sorry if this has been discussed before, the forum search doesn't seem to work?

Debating trading my 2 person tent (REI Half Dome 2) and sleeping pad (ProLite 4 Reg) for a hammock when backpacking without my wife. I am 6'4 so size is a big factor for me. Just wondering if anyone has used either. I have found two brands so far:

I am leaning towards the Clark North America, I'd save 4 lbs carrying it. Specifically I a wondering if anyone has weathered serious storms in one, or temps below freezing.

From the looks of this I might even be able to fit it in my day pack, just in case, http://www.junglehammock.com/models/northamerican/images/phase_09.jpg


I see some of reviews of the ultralight version of both hammocks but I an interested in the heavier ones for both size and heat reasons.

Thanks!
