"Lacking" might be a better word than "simplistic". I agree with him on his points, but it does boil down to the individual. The Hennessys are perfectly good hammocks, not great, but good. There have been at least two polls asking what hammock folks started with and what are they using now; HHs get high marks for the "first hammock" so that backs-up the starter-beginner-newbie claim.
It's a solid hammock system that will work and is responsible for an awfully lot of us getting into the whole 'hanging' thing. It does lack it a lot of areas when compared to some other hammocks; most notably the lack of a zipper. But, they are even moving towards addressing that issue with their Deep Jungle and Deep Winter rigs. In a few more years, Hennessy Hammocks may get back a glimmer of their former fame if they keep on keeping up with what else is going on in this wonderful world of hammocks.
Still, much more often than not, this Cannibal can be found in his Warbonnets while his friends are sleeping in his Hennessy Hammocks.
