I have an REI Halfdome "boxkite". Properly erected, with 10 stakes, it is pretty well immovable. OP shpuld add this to list, as much more usable room than the Passage. I got mine for $50 at an REI garage sale, not a mark on it that I could find. Even better is the quarter dome, but that can be pricey, even in a garage sale. Neither are the lightest of tents, but they are good, and near bomber if erected properly.

Agree that "free standing" is not needed, and leads to a false sense of security. I think my favourite two person tent would be a tarptent Statospire 2, but a) I can't afford it, and b) I prefer, when possible, to use my hammock & tarp set up.
