I agree. Don't worry about multi-fuel options. Many years ago, when I bought a whisperlight, I really liked the fact that I could use white gas, or auto gas, or switch out the nozzle and use kerosene. Over fifteen years later and I've never used anything but white gas <img src="/forums/images/graemlins/grin.gif" alt="" /> So, pick the fuel option you want - liquid, either white gas or alcohol, or canister based, and then find the lightest stove you can afford that does what you need.
