It's very rare that a "What is the best (insert widget here)?" question can get a solid answer. But in the case of a hammock, I am honestly willing to go out on a limb and just say it.

The Warbonnet Blackbird is by far the best hammock on the market at the moment. It is available in weights ranging from
20-36 ounces. I recommend a double layer version personally, and fabric weight depends on your personal weight so that you can still hang with maximum flatness. (I'm a bigger guy, so I go with the 1.7 double, but folks under 200 pounds could easily go with the 1.0 Double in a beautiful coyote brown )

The set-up is much easier than a comparable Hennessy. The footbox provides the flattest lay of any hammock I have tried (and that's a half dozen different models). The gear loft is very spacious, the most I know of in the hammock world. And the side entry allows for use as the most comfortable chair I have used in the back country. You won't be disappointed if you go this route.
