I'm over 20 nights in this tent now and love it. The weight is great - 3 1/2lbs all in, and 1.75 if you run with the fly and footprint only. It's definitely tight for two people, but doable. I bought this thinking I would use it as a one man, but have only slept alone 2 nights. It's very easy setup. By the end of our 10 day trip this summer, we could put it up at night in under 5 minutes. I love the quality and hardiness of this tent. The x style stakes are great and really can't be bent.
My one complaint - It's a front loading tent - so you have to crawl in and out. Getting up at night (us old guys need to water a rock occasionaly) requires a lot of bending and twisting especially if the fly is on and vestibule is closed. My buddy with the Hubba Hubba seems to have an easier time of it with 2 side entrances. Also, when you sleep two people, the front entrance can be a pain. All in all - a very light, very nice tent.
