Optimus Nova, this model:

I like liquid fuels because they're available everywhere and I dislike carrying canisters. This is a multi-fuel stove, making it more versatile. I like that it has all metal parts and is easy to field strip.

Depending on the tour, we may not carry a stove at all. No stove has cascading weight and volume savings: no stove, no pots, no stove accessories, no stove fuel, no bulk foods or spices to carry along because they don't come in one meal serving sizes, etc., etc.
