I've only ever gone traveling with a pop can alcohol stove. I've been happy with it, no real complaints, but I am entertaining the idea of trying a canister stove, namely the Snow Peak LiteMax. I've had some questions about it that are probably pretty quick to answer.
1) Mainly, how long should I expect a 110g canister to last. I realize that this figure will vary greatly. Let's say that I'm boiling 3 cups of water for breakfast and dinner each day, maybe a little simmer at dinner. Am I looking at 3 days? A week?
2) I'm hiking the JMT this summer (first time in the Sierras). I know that it's easy to find canisters around the AT, but how many should I expect to pack? Could I find them at Red Meadows, or Muir Ranch without shipping them?
3) What are the issues people can have with these? I like my alcohol stove because it's just darn reliable (also because it's cheap, but that's beside the point).
4) Anything else I'm not thinking of?
