Going a bit OT but I checked out some
efficiency comparisons between the 4oz brass Trangia burner and ultralight pop stoves.
Pop stoves need more fuel for priming and it is harder to conserve any unused fuel. Trangias burn more efficiently with less priming and you can screw the cap to keep unused fuel. The simmer ring also reduces fuel use.
After a couple of days, the extra weight of the burner is more than compensated by the fuel saved.
Do you use pop stoves with the Trangia wind shield or use a stowable foil one?
