I believe the Cone conjecture is correct. The Epson inks do not appear 
to be 100% pigment inks. I don't believe that Epson claims that they are 
either. I suspect that Epson uses a statistically significant amount of 
dyes in the K3 inks. You can of course do some analysis and determine 
the truth yourself.

The problem with using color inks to make B&W prints, as I see it, is 
that the color inks can introduce problems like subtle color casts, 
color shifting from dark to light, and color casts due to differential 
fading (different colors fade at different rates). While the prints 
might look fine today, what will they look like tomorrow?

It's not worth the risk to me. Clearly, YMMV.
