Has anyone gone from grey screen to white?

I meet the criteria for a white screen (total light control) but I currently use a Firehawk and the blacks are great. I need a larger screen and can't decide which to get. I'm just afraid if I go white, the blacks won't be as good as I am seeing now (realizing the whites would be better).

Thanks for any input.

i would stick with white if it is light controlled. The blacks are just dandy in my opinion.
