Unless those are new and I doubt they are they have just a horrific 
reputation. About six or seven years ago they exhibited metamerism 
that's never been equaled. Rumor had it they were just color ink mixes, 
not actually monochrome inks -- that is, cyan+magenta+yellow to make 
gray. Thus the huge metamerism problem. And they had a reputation for 
clogging too, probably an ink base incompatibility problem. Hard to say. 
That's just what I remember. I'm surprised they are still available. 
That's interesting all by itself.
