Thanks Clint. Do you recommend a particular gain screen? The one I was looking at has 1.1 gain, but considering the throw for a 120" screen will need to be 16+ feet, do I need a higher gain? Also, is grey vs white screen consideration relevant in this case?I'd do the math but I like to have ~12 fL bouncing off at the screen. You'll want/need a higher gain I think, especially if you crank down the iris.
