Why carry the extra 7 oz. when you can (if done carefully) use your canister stove for the same purpose? My canister stove (Primus Micron Ti) weighs 2.4 oz., and I can also cook on it! I'd consider that torch a car-camping item!

If it's that wet, I won't bother with a fire anyway--I'll set up my tent, get out of my wet clothes and crawl into my sleeping bag instead!

I carry an Esbit tab just in case--it works really well to dry out kindling and could be used as fuel if I run out of isobutane. Hand sanitizer works, too, and I always carry that.
