I've done both tent touring and touring with a hammock. I have the Hennessy Backpacker with the hex fly to provide extra coverage. While I really enjoy the sound sleep that the hammock provides as opposed to sleeping on the ground, I have to say that it's an odd feeling not to have the isolation that a tent provides. I've been rained in on two of my tours with a tent and both times was thankful to have had the extra room that the tent provided. I can't imagine spending a full day in the hammock comfortably. For me comfort trumps weight savings every time, so now I carry a lightweight tent and the hammock.
