Gee, I don't know about the hammock; I did it one summer in the 80s (that's not a temperature) - do you actually have to sleep, or just spend the night? (There's a difference, and it's why I've never quite worked up the nerve to repeat the experiment.)

A Svea stove definitely helps identify you as a traditionalist, especially if you're sitting in your sleeping bag, leaning back against your external frame pack (propped up by your hiking staff) while you cook. (I suppose if you still follow the rest of New Complete Walker's or Complete Walker III's technique, you definitely qualify.
