I usually travel solo with a solid fuel system, and canister when with my family. Now considering a solo trip where fuel availability is a matter of concern. After researching the question quite extensively, I am quite positive that I will not use a multi-fuel stove. I hesitate between an alcohol (Caldera system) or an efficient canister (Soto Windmaster) system. Canisters are available in relatively few locations, but never further than 2 weeks distance. Denatured alcohol (or whatever name locals are using) is said to be available worldwide. I am unable to positively reach a decision (ex: alcohol is more tedious to use, takes longer to bring water to a boil, may not be available in convenient quantity -- BUT is cheaper, more environmentally responsible, available everywhere and would add a third system to my kit.)
Perhaps "fuel stories" would help. (ie. have you been stuck somewhere without fuel; have you moved from alcohol to canister or vice versa and for what reason; etc.)
