I used a msr dragon fly on Mt Elbrus for a week from 10000 to 16000 ft. Wind cold snow
Worked great
ribka:
I own a Dragonfly and a Whisperlite. The white gas burns fine at cold temps in both. The Dragonfly does a better job of simmering but it seems to use more fuel than the Whisperlite. I used the Whisperlite at 17,200' on Mt. McKinley and it worked great.
Wind chill seems to negatively affect ISO stoves and I try to build some kind of windshield to counteract this effect. MSR windshields aren't tall enough to work properly. Too bad.
