Anybody had any experience with the Silveryscreen 10 gain screen? I have been trying to get some samples to compare it to other screens. Im looking for a HDTV kind of brightness because there is a lot of light in the room and cant be controlled completely because it is a multypurpose gaming room with bar, pool tables, pocker and that stuff and i can only afford a DPI M-Vision Cine 260 HB projector with 4000 lm output for a 120 inch screen so i need a very high gain screen. But i find what they claim at their website to be like "Snake oil" it sounds to good to be true, besides i havent found much third party information about it. I have other options like Stewarts Firehawk 3G which i think its a good option because it is a grey screen with good gain so it can serve double purpose to improve brightness and black levels. Other options might be SI black dimond 2.7 but i think the biggest size is 115". So what do you guys recomend?
