In reply to davidbeynon:
I've used the trangia multifuel burner a number of times, and although it is a fantastic stove combination there are a few issues we found. Aside from being rather heavy, it was also quite prone to getting clogged up, and cleaning it wasn't as straightforward/simple as other stoves I've seen. Also the dimensions weren't quite right, and to get it to fit snugly in the lower windshield required it to be bent to accept it. I'd imagine this may have been fixed in a new design, if there is one?
Having said that, it is a pretty damn powerful stove that when set up in the doorway of the tent on a rainy evening managed to give us both sore heads by using up all the oxygen, something I've been quite wary of since! It can also starve itself of sufficient oxygen as the windshields don't allow enough ventilation to the burner when it's turned up high and a pot is on the stove.
