I hear ya, but 20+% bigger and still lighter... always costs more.
Since I have that Tigoat bivy already I guess I am pretty set. But your right - I don't know if it is 2.5 times better....I try to get the right stuff and be done with it. So I can worry about where the game is instead of wondering if my tent is up to it. Given my sewing skills I'd probably ruin a couple Go-lites in the process of adding a stove port. grin
