I currently live in restrictifornia and have to use a canister stove. I keep two small canisters with me so when one runs out I have the other to use. When I get home I refill them from the larger canisters. I have the Primus ETA
setup. I don't use their heavy zippered simmer storage bag. I don't like the freeze dried food in the foil packets. I buy the No 10 cans and put the food in zip lock bags. I only boil water in my pot and add food and water from the pot into a cozy with a screw on lid. I also carry a MSR fry pan for cooking other foods.
