Take a serious look at the Hennessy... you mentioned getting older, sleeping in a net puts your body in a curve that's hard to shake off in the morning. In the HH, you sleep on a diagonal with the tie off points that leaves you laying almost perfectly flat, hence a whole lot more comfortable. As a member of the "over forty" club, and cursed with arthritis, I can tell you first hand, the minimal weight difference is well worth it. As for room in the pack, if you get the snakeskins Frenchy mentioned (yes, I've got them too), you can sling it over your pack, alla WW I G. I. bedroll style, or over your shoulder like a bandolier, either way, no lost space in the pack.
I've got nothing to do with HH other than being one VERY happy customer, but I gotta tell ya, it's some of the best outdoor gear cash I've ever spent.
