I do not yet have a camping hammock, but I am preparing to set myself up and give it a try. My hanging experiences so far have been limited to a backyard rope hammock, in which I regularly become comatose within 30 minutes.
Most of my camping is done while motorcycle traveling, so although weight isn't a big deal, bulk is. I "tried on" somebody's HH (can't recall the model) at a campout last summer for a few minutes, and have not been able to stop thinking about them. I like the idea of not worrying about clear ground, wet ground, and I like the versatility.
I am 6'2" and about 180lbs. , so I am looking at the HH Explorer or WBBB (although I am open to other suggestions from the cognoscenti).
