Digital BW, The Print

I have a 1280 and have been using the UT inks for printing.  However, I 
want to do warm tone prints on the printer and have looked on the MIS 
site and found the FS inkset for the printer.

I would like some up to date information on what is the best ink to use 
for the 1280, an oldie but a goodie for b/w prints.  Thanks, Mike
