With any of these ink sets, it is in fact the black that tends to be 
the most stable. The shifting that occurs as a reaction between the 
ink and paper coatings is mostly in the lighter inks.
I've been using Piezo inks almost from the day they came out in two 
model printers, never had clogging problems. All of my MIS prints and 
new MIS tests I've seen have been greener than Piezo.
Good luck
