I'm using either a GSI Soloist pot, which is what I bring when my wife and I are out together, and when I'm solo I use a Wally world IMUSA 2 1/2 cup aluminum cup.
I only boil water, and when the water is about to boil, or just starting, I turn the stove off, mix my meal, drop it into a cozy, button it up, and wait for 10-20min, depending on the meal, and then presto, eat up. I've experienced great results, with food still hot enough that I have to blow it on it to cool before eating.
When I use my Litemax, I don't crank it wide open; I only put the flame out to engulf the bottom of the pot only. I always use a windscreen, and am really precise on where I cook at. If temps are cool, its normal for me to take the cannister to bed with me to make the cannister more efficient come morning.
