You have to use what will work and what you like in your environment... and everyone's environment and tastes are just going to be different!
I am sure that is true. I know I could probably double my screen brightness by moving my projector up close to the screen, but this also has its disadvantages. Contrast level would decrease, uniformity of focus would probably not be as good, zooming to 2.35CIH would probably be more difficult or even impossible, fan noise would be right over the audience, and the room would not look as good with the projector hanging in view from the ceiling..
It is all a compromise, and as you so correctly say, everyone has to do what works best for them, and there really are no hard and fast rules in home theater projection. One of the things that makes reading of other peoples HT experiences , and set-ups on this forum so interesting.
