So I'm thinking about adding a 4-place O2 system, but I'm kind of stymied as to what size cylinder to get. For those of you that travel a lot, how often are you going up into the mid-teens at cruise? Currently I cruise between 8K and 10K so don't have a clue if climbing higher is something that would become routine or just be an occasional thing.
