Wow, some really good points brought up since I last posted.
I'll probably still stick around to help out those who are planning to build a curved screen or who want to rock the DIY boat by making a screen using XD material. Apart from that, I'm stoked about my screen and am looking for other ways to make my theater better. I was initially focused on the video aspect of my HT, but man am I ever loving how much of a difference an AT screen with good speakers can make on the whole experience. I'm now in the process of putting up acoustical panels and then I think I'm done...for now.
