Paul,

for the sake of  statistics: I have not had clogging problems with Museum 
Black in a 9500 - nor with FSK in a 7000.  Haven't tried Eboni yet - waiting 
until the dust settles a bit.  But if Eboni had similar viscosity/particle 
size/chemistry to Museum Black (MB), I would expect it to run equally well.

Of course this may not say anything about desktops. I have OEM / UC inks in 
the 2200 and the dmax of MK is similar to MB on matte papers, which 
suggests a "family resemblance", but perhaps not much else.

One thing that is still a question: is there something in the new Epsons 
(22/76/9600) that deals better with these inks? If so, making a clone of the 
UCs and loading them on several-generations-old desktops may not be a 
good idea.
