BradMT, another double wall tent you may want to look into is the light heart solo. Its basically a 1.5 man tent with options for customization. Its not cheap (otherwise I would have one already), but it is sil-nylon and only weighs 27 oz for $245. There is a cuben version available also but Yikes! on price. I've been interested because I usually bring my dog so I need a 2 man tent.

Side note; I also don't like the door on that particular Big Agnes. It is much harder to keep things clean.
