I use a Coleman Exponent F1, a cannister stove like the Pocket Rocket. Hard to beat the ease and simplicity and feather weight. A two week trip? Two cannisters if you cook every day. Still lighter than a bottle of fuel and all of the attendant assembly, mess, cleaning, repairs (and repair kits), etc. The Coleman Exponent Feather 442, a dual fuel stove, still one piece, self contained fuel tank, quiet, reliable, packs easy—is now my back up. MSR makes good stoves and no mistake, but screw all the hoses, windscreens, fuel bottles etc. Some folks swear by the JetBoil, but I'd just as soon take a coffee percolator if it came to that. When someone starts advertising "system," I look elsewhere.
