Hi, I'm building my own screen and decided to get the High Gain material from DRH - this appeared to be in the middle of their other two products - cheaper that the High Colour stuff, and slightly more expensive than the standard Mat White. I thought the High Gain is what most people recommend as it is about 1:1.2 gain - but when I phoned to order it the chappie said that he doesn't do the High Gain anymore - just the Mat White or High Colour. He said that 99% of the screens they sell are all Mat White and this stuff would be fine - so I've ordered it - but thinking about it now, am I loosing out on performace from this 1:1 stuff - would I see a benefit by getting a higher gain material ? I'll be running a Z1 when it arrives. Ta.
