[pct-l] question re canisters

[Town Food]

I haven't used it, but the way I look at it, an entire canister is 4oz. 
So if the JetGauge weighs 3oz, you'd do better to just carry a spare 
canister.

(I say "better" because canisters, unlike the JetGauge, get lighter over 
time as you use them.  So on average a canister would weigh less than 3oz).

I never quite tested that out myself, because running out anywhere other than the last moment before a resupply would mean uncooked food until I got into town.  So I'd buy a new canister when my current one felt "low" in town.  It might be worth trying to train yourself to feel how full a canister is.  Either by weight, or by swishing it around and listening/feeling.
