At this point, I've gotta say it's the GoLite Shangri La 4 with a stove jack in it. I love my megamid, but dislike that it doesn't pitch tight to the ground. Not an issue in snow, but somewhat breezy elsewise. At 3.5#, the SL4 is quite a bit larger -- almost the size of the Kifaru 4 man which weighs nearly double.
