i've used propane exclusively: simple,light, compact, easy to light.
dependable ,quiet,clean,simmers perfectly.
i've never used add-ons, just made it work for me. i always cook inside.i keep the can wrapped against my back in my pack and in my bag at nite, if it's super cold, otherwise i forget about it. i've used it INSIDE my sleeping bag to dry it and to warmup, on super low.
climbed 30+ mountains in winter 5000m+ with it.
melted and cooked at 7200m in a feezing himal ice cave for 2days. IT WORKS!
of course , for big fast pushes, big groups,or extreme cold, xgk type is better.
