I don't have any first hand knowledge like you, but I am curious to know what type screen you are using and what your light control situation is. Those are very important issues when dealing with a fairly low light output projector. The reason for asking is if you look at projector central's calculator they don't go above a 96" wide (110" diag) screen for the VPL-VW100 projector and at the 96" width they recommend a high gain screen. The 200 also shows low brightness at 123" diag, btw, but it does up the lumens from 800 for the 100 to 1,000 for the 200.
