I've had one bad experience with an old canister stove and been using white gas stove all my life, mostly because of fall and winter hiking trip. I'm currently using a MSR Dragonfly which is rather heavy, very awkward to pack and f***** LOUD! So loud I'm embarassed to use it in public campground. I've taken it on planes with no washing. I just aired the bottle well. White gas evaporates quickly.

Next time I'll probably bring a home-made alcool stove: Cat stove.
