Digital BW, The Print

I need some advice from experienced Epson 7000 users. Has anyone out there 
successfully used this printer ( or the 9000 ) for use with either the new MIS UT pigment 
monochrome inksets or the Cone ICC Piezzotone inkset? And, would there be any 
difference in the consistency of the new Cone or MIS inks ( back position? ) in comparison 
to the last generaton of mono pigment inks which evidently performed fine in these 
printers? 

Three of us out here have had head issues since installing carbon pigment inks in the 
7000 this past week. Am I just paranoid or is this a bad combination? I need to know if it 
is time for me to hang myself on Monday.

Any thoughts would be helpful,

John
