we used 2.5 lbs of canister gas for 10 of us. We took 3 titanium pocket rockets, 2 to heat water, one as a spare. We used turkey bag cooking method (boil the water in the pot, put the hot water in the turkey bag, dump in the dehydrate, squish, shake and let it sit). Followed by consumption then human sumping of the bag, viola', your finished with KP and off to another activity.
Worked very well, we'll do it again in 08. We did the math, and in the long run, it was the lightest weight for our trek.
See you there in 08,
