I've researched various brand canister fuel ratios and have managed to come up with the following ((butane, isobutane, propane)
Primus - 70%,10%,20%
MSR - 0%,80%,20%
Coleman - 60%,0%,40%
Brunton/Kovea - 0%,70%,30%
SnowPeak - 0%,65%,35%
Jetboil - ?,?,?
For the first 4 listed, I'm reasonably sure I've got the ratios correct (which means I've been able to confirm from multiple sources). However for Snowpeak I've seen different ratios claimed, and I can't find any info on the Jetboil canisters. Anybody know these ratios definitively?
Anybody care to share what their experiences are with regards to the lowest temps that they have used various brands of canisters down to (and still gotten good results)? I'm looking for inverted use especially. Thanks!
