Thanks guys!
alakso, that was the only tent by Exped that they had in store. The person manning the tent 'floor' of the store didn't know very much about the Exped tent, this is why I ask.
and thank you, fishstick, for your endorsement of the Sirius - great to hear that it's holding up well.
In particular, I hope to find someone on this board who has this tent and has used it for a while. My Google-fu is failing me, all I find are ebay links and other commercial links - but no reviews or comments from users.
My one-person tent is the Hilleberg Akto, and I'm very happy with it. I noticed that some of the construction details in the Exped tent were similar to the Hilleberg's.
