I was one of the guys who posted photos from the BPL gathering at Henry Coe SP. The Vargo was up against a Caldera Cone, Bush Buddy, Backcountry Boiler, Ikea Stove, and maybe one other. It was hardly a controlled test though, more for fun. Different operators, different wood sources, starting fuel, and unmeasured amounts of beer consumption :) There was also no wind or rain that day (though some light snow). Some took longer to get their fires started than others, and in the end everyone got their water to boil.
