Jim,

Another good review. Thought I would pop in here with a comment about using butane canisters in cold weather. As you note, everything with stoves is a compromise. Necessity being the mother of invention, I discovered some years ago that one of the hand warmer packets (like this: http://bit.ly/eAFc4o) will do wonders for cold weather performance. Never did any testing to see how low they will help with, but it was at least a few degrees below zero (F) when we used 'em.
