Alan,

>... Has anyone seen a durability estimate for [MIS] pig/dye black? 

No, but I don't trust any dye.  My bottles of MIS black dyes and Media
Street's hybrid black collapse onto themselves in my darkroom storage as the
oxygen is sucked out of the air in the bottles by the fast oxidation of the
dyes.  These are not stable products.

>... what about the MIS sepia ink?  Is it a pure pigment or a tint 
>made with the archival colored pigs?

It's a tint made with color pigs added to carbon.  The UT2 sepia ink is 84%
UT2 light magenta ( magenta is the un-toned ink "color" position in the UT2
inkset), 8% MIS 7600 Y and 8% MIS 7600 M.  It can carry the entire print all
the way to 50% (no other inks) and make very nice dark sepia print that is
very close to the tone of the Getty's Gustave Le Gray historic prints (what
I used as a model this time).
