I will be doing 6 days and 5 nights in Yosemite late August and was thinking of buying an additional stove (currently have a Primus Multi fuel heavy and old). There will be two of us and all we will be using the stove for is evening meals. Essentially boiling 32 oz water each night.

2 Questions:
1. Anyone have any bad experience with the Snow Peak Giga?
2. Anyone provide a rough approximation on how long the canisters last? My guess is I will need 2 maybe a 3rd just in case.

Thanks
