Used those canisters and that stove for years, never had an issue with leaks. That said I carry a single wall cup which I can use to boil water in a fire if need be. I usually have a small fire at night anyway. Often use hardly any fuel. I would never carry a double wall cup or nonstick cup/pot for this reason--you are marrying yourself to your stove which is pretty silly in an emergency situation.
