I have one of those camping propane burners that screw on top of the little propane tanks. So I was reading that the butane burners are better for 3-season because the fuel is lighter that propane. So I bought myself a butane burner and grabbed a canister of fuel. On the good side, the butane burner is much smaller and lighter that the propane burner, so in the end everything worked out well and I reduced weight. The bonehead move was grabbing a 1 lb bottle of butane to replace the heavy 1 lb bottle of propane.
