the "empty" canstier is my stumbling block.......when I empty one, I'm fairly prompt at getting it holed and into the recyclebin. and to add confusion, I have a few canisters that are "partials"....I'm currently in the plpanning stage of a lenghly hike for this summer. the tenitive plan is, during this hike I'd like to depleat one or two "partials" before reaching for (yet another) fresh canister. -if the "partials" look good enough, then there'll be no need to pack a full one. of course all this could be done by weight- but that dosen't lend it'self to monitoring fuel usage while on the trail...and I could be wrong, but an empty would still be required to start either caculation/evaluation
