I figure my ultralight wood burning sytem weighs less than that - it's three rocks. I carry nothing. I find three rocks and build a twig fire and put my pot on top

if I'm dual fueling it, it's the above system plus my penny stove, potstand, and windscreen.

Fact is, anywhere I can (legally) use a tri-ti woodburner I can also build a little fire (at least up here) and then I don't need to carry a stove at all for burning wood.. that's the ultimate ultralight option
