The Luxus is one of the ones that I would go with for sure. Likely a good deal more expensive than the Draper listed above, but a high quality screen for sure.
The Firehawk material is not listed as one of the materials available on that particular screen design. In general, grey screens may not do a lot for you in a theater black environment, but help more when lights start going on. If you have any intention of having some ambient light in the room, then Firehawk would be a decent choice. Otherwise, Studiotek would work as well, and may provide a more uniform image.
Sucks about the WAF issue... Family room?
I personally went with an in-ceiling motorized screen that retracts all the way up into the ceiling. When it is retracted, there isn't even a screen hanging on the wall to draw attention. Most first time guests don't even realize we have a projector in the family room. Pricey, but very nice and huge points for WAF.
