The snowpeak gs100 is in the same fuel efficently leaguge as the pocket rocket. I found that I would get around 40 minute of high heat from the small snow peak canister, and around 80 minutes from the larger canisters from MSR, Primos, etc.

The question is do you really think you will be using the stove for 40 minutes on high / day? My experience is that I could boil 7 1L pots of water or 12 24oz pots using the small snowpeak canister most conditions. Since I only cook dinner, and for dinner boil 24oz... one canister lasts me a long time.
