Many backpackers love their gas cartridge stoves due to their ease of use. For those of us who use them on hunting trips I'd suggest that the INVERTED canister stoves are the way to go. This is because they will work in very cold weather when the upright canisters will not. Look at REI and other backpacking online stores to find these stoves. If you already have a decent white gas stove like an MSR Whisperlite, Whisperlite International or Dragonfly then just use that for the ultimate in cold weather reliability. Of course there's always wood. But here I'd suggest buying a Trail Designs Tri Ti or the shorter Sidewinder stove with the Inferno woodburner insert and matching pot. (This is a must for maximum efficiency.) This stove is HOTTTT! because it uses gassifier stove technology which burns initially unburnt combustion gasses between the double walls of the stove. These stoves use finger-sized sticks and keep flying sparks to a bare minimum while utilizing the wood fuel to the max. Plus these two stoves are very light and will burn ESBIT fuel tabs more efficiently than any other ESBIT stove. I've experimented a lot with ESBIT and these stoves are by far the best. Nothing else is close for saving fuel and giving fast boil times.
