During my July Baxter to Monson sopping wet hike I carried both my Featherfire, my Bakepacker lite cook pot and a Heineken Penny stove with a little four cup Ti pot. My main reason for carrying both was the desire to experiment a bit with the Bakepacker which doesn't work at all with the Penny stove's burning time. The Featherfire burns about 16 minutes with two oz of fuel, and the Penny about 6 minutes with one oz. Most of the recipes and Adventure Foods dehydrated meals required around ten minutes of boil time in the Bakepacker.
For the seven days through the 100 mile woods I used about 28 oz of denatured alky. Had I used the Heine Penny stove and FB cooking I would have carried less weight and used half the fuel.
I used the FF supplied windscreen with both stoves and will continue to use it even when I leave the FF stove home.
I had no issues with wind, and more often than not didn't even use the windscreen.
Bottom line: The FF stove worked well, but weighs much more than the Heine stove and used maybe twice the fuel. However, the FF does allow you to extinguish the flame and recover the unburnt fuel and is a simmering wonder.
If I want to go as light as possible and don't want fancy stuff like biscuits, pancakes and cakes I will leave it in the equipment locker. Adventure Foods seems to be out of business and after eating some of their meals I understand why. The meals I had were donated to me and are all gone now.
Got to say, that their omelettes and huevo rancheros were darn good but the other meals not so much.
