Harp is right. I cannot ever recall mixing a 5:1 LW. And I have no sample of it. Hold tight on that until I mix one up that I can spectro! The thing is it could have been one of the sample sticks that I did and tossed after spectro'ing them. While the numbers jive with everything, let's hold off on mixing it up until I can verify it.
Harp - you never did a 5:1 LW did you?
I'll mix one up in the am tomorrow for measurements tomorrow and Thursday.
And again, if you feel you need a lighter screen, CGiv is a great option as well!
