We backpacked with Peak 1's for years. We used to chuckle at they guy in our backpacking group who would insist on bringing his Bluet along. Compared to the Peak 1 it never cooked well at 10,000 feet and the lowest temps we were in were 25-30 deg F in the mornings.

I bought a MSR Whisperlight international myself for backpacking and disaster. During my ultralight phase I bought a Snow peak stove. I like to use it for day hikes and low altitude fair weather hiking.

I owned a MSR Dragonfly which is a water boiling champ but way to loud so I sold it. Diesel burns a neat white flame in the Dragonfly.
