I asked the same question a while back and the general response was that they are really heavy, so I went with just a tarp. I still want to get one though just to try it, I just went with something I knew would work for me.
I think you should try it, although like I said lots of members here told me it wasn't all that lightweight. Clark Jungle Hammocks are really light though so, if you have a bunch of money that could be an option too.
