Tom, welcome,

One big problem you may experience using the Epson pigments for BW is their
relatively high metamerism. Now, I know Epson is working with the GCR of
their printers to help with this (means mixing a higher percentage of black
ink into the desaturated and neutral tones, since it's less metameric than
the color inks), but I haven't seen any BW prints from a 10000 to know how
effective it is. I only know BW prints off a 2000P were very objectionable
to my eye, as they were usually garishly green in daylight.

So, the quads are much less metameric than most if not all color pigment
inks. The other thing with the quads is when they fade, and all inks will
fade, they fade gracefully to warm, whereas the color inks may fade in any
direction depending on what color in the set is the weakest link.
