This depends a lot on the tree you camp in. Many trees have quite
substantial branches, making it easy to attach a couple of fly-lines.
I use a Hennessey Hammock in trees with some success, and before that
used a home-made one that worked in a similar way. Be aware that you
are more likely to end up falling if you hang the hammock between two
trees high up - the tops move much more than the bottoms (and mroe
than branches do relative to each other).
Currently I run a length of 6mm rope out through the slit in the HH,
but ideally I'd like an opening in the side and a quickdraw sewn
through the top of the netting. I haven't down that yet though.
I suggest you add a hauling pulley (only goes round one way) to your
collection, as that makes it much easier to bring stuff up into the
tree. When cycle touring I occasionally find it useful to camp 20m or
30m off the ground, and lifting something that heavy you need at least
2:1 pulley advantage (80kg or so). So it depends on what you're
When you're up a tree, it's often useful to have a "gear hammock" or
something that can be stretched out to make a more or less flat
surface. Otherwise cooking and so on can be a real pain, but that also
depends on whether you want to go down to cook. I'm used to trees
where that's a real pain (descend 30m, cook, climb 30m? I don't think
so). I carry a 70cm triangle of doubled ripstop with gear cord edging
that makes biner loops in the corners. So I can sit on it if I want
to, but normally I just put gear on it as I unpack it. The HH in
seat mode is not a good place to put things - it's too liable to shake
and drop your gear.
