I've had problems at trail camp starting a stove with a cold canister. But generally been able to work it out. Separately, the autoignite is definitely tempermental when the canister is cold. Matches are a total must.

I've read that MSR uses a better gas mix than the others in its canisters. I usually use Snowpeak (I have a Snowpeak stove) but I understand that, notwithstanding the mfrs recommendations, any isobutane canister with the standard threading may work. I haven't tried this myself much and can't claim to be an expert on this topic. Hiking Jim is the resident stove expert. http://adventuresinstoving.blogspot.com/
