Slight cost difference I know, but room will be multi-use with slightly subpar light control. I've read comparison to the Rs2,but the increased lumen of the rs1 will probably be needed. Projecting to stewart screen and would eventually like to do 2.35 aspect cinemascope...?

Just zoom for now.

You mean VPL-VW60? There are many comparisons of those two if you use the search function.
