I'm a "hanger" myself, so I do want to warn you of one thing: Hammocks will require an additional investment for an underquilt or you'll freeze in cooler weather. Also, the dinky little fly that comes with a Hennessy will require either replacement or you'll need a water resistant underquilt protector - cuz if your underquilt gets wet, you're screwed..
I will tell you that Hennessy makes a great product. SnugPak seems to have developed a reputation for poor quality - which I can attest to. Several years ago I bought one of their packs and it was unacceptable. I returned it. However, I have some recent SnugPak stuff (a couple of sleeping bags, underquilts, overquilt, cocoon bags and a tent) - and the workmanship on them is now quite good - I'd even go so far as to say excellent. YMMV.
