The gas you get for the Jet Boil, fits in the cup, as well as everything else, also it last well over a week, so their is not that much weight and easy to find. Also it lights in high winds and snow and you can pack it away as soon as you are ready to go
I have tested and used, i think nearly every stove, cooker device there is even the coke can stove, for me the Jet Boil rocks
