Im considering that material from that seller in the for sale sections from BuildYourOwnProjectionScreen dot com. It shows a 1.2 gain, which is near what im looking for. Right now im using just a parkland plastics 85" X 48" screen. Heres the sad part, haha. Im using a Sony Ruby (bought it off the forums here for 1620 shipped). I really cant spend more than 200-300 right now on a screen and I know... that doesnt do the Ruby justice. Some might say to not even bother until I can spend more, but because of the location change, I kinda need to make a larger screen, like 120"
