Having the PJ upside-down is not an issue, it's more the distance from PJ to screen that I'm worried about. Looking at the screen size calculator on projectorpoint it looks like a 110" screen is not going to be big enough to deal with the distance between screen and PJ however the 9000 will manage this. Looks like I'll need to convince the Mrs that a 9000 will be worth the extra pennies
Is there that big a difference between the 6000 and 9000 in light conditions? My livingroom is not that dark at the best of times so even with all the blinds closed it is still quite bright during the day

. I know the 9000 has a much better contrast ratio but would blacks really be that much better in daylight? I take it a matt grey screen would be best for these conditions? This will be my first PJ so I wan't to get all the right stuff first time round
