John,

Yes, I wouldn't want to substitute another black to use with the  
neutral k7 inks, but I could use another black (museum, eboni, or  
portfolio) with the carbon sepia inks.  I'm not sure yet what I'm  
going to do with the PK slot (currently holds a cleaning cart).  MIS  
PKN for printing BO on epson premium semi-matte (I like this for some  
images) is another option I'm considering.
