Let me start by saying I'm a huge fan of this forum, I'm looking forward to your advice.
I recently picked up a pt-8000ae, putting it in a spare basement room, so very controllable light sources. Seating is 10.5 feet and the throw is 165 inches. I currently have the projector installed and am projecting on some foam board so I can get an idea of sizes. Here is my quagmire, I tend to like an overwhelming screen experience, ie 120" for 10 feet away. I have a few reasons, my kids like to play Xbox and they always split the screen into 4 quadrants, so having a bigger screen seems to work, plus i do want it viewable from other rooms on the rare superbowl occasion. Do you all think that is too big?
Also, I really don't want to spend 3k on a diamond screen, ESP with such a controllable room. My question is what would be best? I couldn't find a great answer with the penny 8000. I'm thinking painted, but could sure use some advise.
