Scott, I don't know how I managed to not read your thread until now!
I enjoyed watching the progress, and also glad to see you didn't keep up that pace for the whole build!
It makes me feel better about myself.
I absolutely love, love, love, the material choice you made. I'm going after something similar. Your entire thread will be helpful reference to me as I progress myself.
My screen is the exact dimensions you have, but I'm going with the seymourav material. Most say it is the same stuff. I was curious in your comments of the screen being a bit too large for front row. I've got mine mocked up on the sheetrock, and it is borderline. But I can't help but feel that future projectors will grow right into the 12' screen size! Although, your screen caps looked great! Any further comments on screensize now that you've lived with it for awhile?
