Digital BW, The Print

This is a question about the UT2 inks for the Epson 1280 printers. 
MIS says that the Eboni K is used for matte papers and the Photo K is
used for glossy papers.  Paul Roark's site says you can use the Eboni
for glossy too and just need the curves.  I would be doing this as a
test but might want to occasionally print on glossy paper.  Would the
Eboni or Photo K be the best to use.

Also, how is GLOP used with the UT2 inksets?

Thanks for the help.
