BB9,
I don't understand and the reason is that a half pound over the course of a day really adds up, especially when it is at the end of your fingers. Go to an ultralight backpacking site and browse for a little bit. What those guys do is basically what I and Elkcrazy8 and a lot of elk hunter do. Put on a LOT of miles at high altitude. They will spend $200-$300 to buy a camp stove that is 3 oz. lighter than the one they have. Not better, but LIGHTER.

If you want to put this in perspective. Find the biggest hill around your area, put a plastic bag over your head and poke a hole the size of a pencil in it to breathe through, and walk up and down it all day from sunup to sundown and tell me if you wouldn't wish you had lighter boots, lighter jacket, lighter pack, etc.[X(]
