I wasn't trying to downplay the idea - let him among you who has less than 3 stoves cast the first canister, right? You've almost convinced me I need to buy a Superfly just so I can play around with my PocketRocket and (when they start releasing them to us mere mortals who don't test stoves ) my new MicroRocket. NOTE: I'm writing this from work, and don't have a stove to look at - I can't remember whether the valve can detach from the PR, and if it can, whether it's the same size. Now I've got something to do at home tonight.
