Hi Daniel, I'm one of the Brits you will be hunting with, you just missed a good deal on an sl3 in the classifieds.
I have a Hennessy hammock and the country we will be in would be ideal for swinging one, but I wouldn't personally use it there for reasons mentioned above, freeze your @*ts off unless you pack under quilts which puts the weight up to that of a one man tent or more, lack of space etc. It would probably be easier to find a hanging place than a tent pitch at times but after our last visit there and all the storms and rain its a tent for me.
There wouldn't be room for you in Dave's tent and your not getting near the inside of mine, so don't worry,
