I use a single wall of the Caldera Cone as a windscreen for a pocket rocket. Works great. I tried a variety of myog windscreens but they were all fragile or complicated. Plus,in a pinch, I could use the Caldera to make a wood chip flame and boil water that way.
I haven't tried many stoves, but in defense of my pocket rocket I'll just say that it's super light, reliable–never failed me–and robust. I've had mine for many years; never an issue of any sort. With a windscreen it's remarkably efficient. But I'm a solo hiker, boil-water-only kind of cook.
