Scott, I have a ring of fire stove that I have used in the field with my Heineken pot. I really like the how easy the stove is to set up. I am not so thrilled about the weight. 2.25 oz for just the stove. 2.9 oz for the stove + windscreen + reflector vs 1 oz for my tealight setup. Want to point out that I use the same windscreen + reflector for both the tealight and the Ring of Fire. Although I flip the windscreen upside down (holes up high) for the Ring of Fire.
In colder conditions (early morning cooking with water sitting out all night ~ 40 degrees) I have not been able to get 2 C of water boiling on 1/2 oz of fuel. However, the water has been warm enough to have warm rehydrated food. If I cut the water to 1 1/2 C, which is what I usually use, I have brought water to a rolling boil on 1/2 oz of fuel in the field at 11,400 feet in dead calm conditions.
I have tried the Ring of Fire with a regular cookpot but found the stove lifters (tabs sticking up from the side of the stove) too short. The flame would just go out. I tried this several times in my house with different amounts of fuel and without a windscreen with the same results. So I ended up just removing the tabs and dedicating to use with my Heineken pot.
For a traditional pot I would just go for the Super Cat stove.
