guess I'll ask the question in the proper forum now

huge news on the pricing, pulls me back from all the brighter pj's I was looking at. Question for the group: I have a new, large room, non-light controlled (for daytime sports) but which can get quite dark (so a high contrast pj is still worthwhile). I am currently using a holdover ae900 shooting a 144" (like it BIG) picture at 17 feet. the PC calc says that's 7FL on the screen. It is clearly no good for daytime sports but works in the evenings. The PC calc says the 3000 would put 11FL on the screen with those specs - I'm assuming the 4000 will be higher. Will a 50% increase be enough for the daytime viewing (bad blacks and all) or do I have to give up all the cool features of the 4000 and stick with one of these new, bright dlps?
before anyone asks, I've tried the epsons, they are certainly bright, but I (and that's all that matters, if you can't, good for you) can clearly see the pixel structure on the epsons and that kills it for me. If I'm going with LCD again it's smoothscreen or bust. Thanks.
