Is the tablet stove that much lighter than the regular stove? My canister stove weighs nothing and the canister does not seem to weigh much at all. What is the benefit of using the tablet fuel?
Various places on the web say a fuel canister weighs 4 oz and holds 8 oz of fuel, and lasts 10 days. I think you can find smaller canisters (4 oz?), but what I read shows they weigh 8 oz total.
The pocket rocket stoves weigh about 3 oz. So with the smallest canister and stove, you are carrying 11 ounces. The Titanium Wing stove and two fuel tablets weighs under 2 ounces.
Along with that, the canister stove takes up more space, so you might need a bigger pack, adding more weight.
The difference is not much to many people, but for ultralight fanatics, the difference is important.
