The point is I would have to ceiling mount with the Sony vs doing my normal rear shelf mount and that means getting considerably less gain out of the HP screen since the closer the projector is to eye level, the more of the 2.8 gain you get. The shelf mount is MUCH closer to eye level vs doing a ceiling mount.
Whatever brightness advantage a closer mount would bring with the Sony with unity gain type screen would be offset by the fact that the 45 is brighter to begin with (for 2d at least, not sure about 3d) anyway
That is the other nice thing about the 7000 Chuck is I can rear shelf mount that pup as well which should give me squint inducing 3d brightness!
