OK, here is what I am going with, unless somebody believes that I really should try something different. Keep in mind I am in a light controlled dedicated HT with dark green walls and drywall ceiling painted black
SW7071 w/25% Minwax CSP and 10% DW
Original Screen of Behr SS, UPW and WOP
I have leftover Behr paint from my original screen, so I think I am going to splurge and get a gallon of the matte SW7071. I am going to paint a separate piece of drywall in 4 sections and compare it with my original screen. I will try to take pictures and post them. I don't have a great digital camera but I will do my best. Hopefully I will have some info by Monday.
oops - thought I had some Behr SS left but I only have it mixed with the UPW and the WOP.
I am getting some screen samples from Carada and Da-lite for some comparisons.
I will probably wait until next weekend to do my comparisons, giving me time to paint a couple of coats on my sample drywall.
