All-in-One and the WOW factor
Derek really gets it right about the benefits of all-in-one. When I camp in an ENO or in a DIY rig, people are interested and ask me about 'em. When I sleep in my Hennessy, they're fascinated. I think the pull-outs and the bottom entry really helps sell the whole package benefit. And I have had many very happy nights in my Hennessy.
But I hate the bottom entry. I'm not modding it because I've got other hammocks I can use, and there's some pleasure in a non-fiddled-with setup. I have even kept the original suspension, even though I have a couple of currently unused whoopies in my gear box. Because, to be honest, Tom Hennessy is a smart guy, and I am still learning from his design. My DIY hammocks are better by learning from his.
I still own, use, and camp with my stock Hennessy--because it is, really, the standard against which I judge all other hammocks. And most of the time, the HH comes out ahead.
