Mike;

About 1 1/2 years ago when I started my exploration of trying to get
decent B&W prints out of my Epson 1200, I started plying around with the
Photoshop supplied Duotones. On some images I was able to get a nice
grayscale with little crossover, but this varied from image to image.
However the big turnoff was the amount of metamerism with the OEM <pre
lightfast> color inks. The prints would look great under tungsten light
and VERY green under daylight. In comparison the Piezo and MIS quad inks
have almost no metamerism.  

Are you saying that the newer Epson "lightfast" dye inks have less
metarmerism then the standard Epson inks that are in the OEM 1200, 1600
color cartridges?
