"Yes, the XGK is very powerful. However:
XGK Minimum Weight 13.2 oz / 374 g
XGK Packaged Weight 1 lbs 1.2 oz / 489 g
Snow Peak GST100 78 g
We are, after all, keen on light-weight gear."
I expected that kind of response. Those numbers are meaningless because neither stove can function without its fuel source. So, do the math with numbers based on, let's say, four hours of fuel in bottles or canisters. Then, I don't know about you, but I have to figure in a cost factor on fuel. I hate to use a butane canister that has to be disposed of.
The one thing that I do like about a butane canister stove is that there are fewer moving parts. Also, Everest climbers like them, because at extremely high elevations, the whole butane vaporization issue when cold becomes less and less of a problem. However, we don't get over 20,000 feet very often these days.
