I just picked up a winnerwell titanium stove for a SO Redcliff. It has a slick, hinged set-up that makes it easy to get going when it's dark and your hands are starting to get dumb. Heats the redcliff nicely thus far (lows into the 30s, which isn't a great test).
But I'm not to thrilled about how airtight it isn't. Here's a bad camera phone pic to show all the leaks from the door warping when fired, around the non-welded flue collar, and through the hinges on the side. Fixable with mods, which I have yet to do.
I like how packable it is, but I carry a bigger tent stove in winter, when I'm towing a toboggan.
