Digital BW, The Print

Well, I've tried the MIS Ultratone7 MIS inks (cartridges) on an 
Epson 2200 and I don't like them. Even with Paul's curves, to me, 
they're muddied compared to OEM Ultrachromes with Imageprint.  I'm 
primarily working on either Photorag or Moab Entrada Bright White.

I'd appreciate recommendations of CIS alternative systems for my 
Epson 2200 - either B&W only or color (for use with Imageprint 
though).  Absolute requirements are that: (1)they be archival, (2) 
they be pigmented,(3) they be compatable with Imageprint and (4) 
that they be capable with Imageprint of producing B&W prints without 
a color cast -- whether green, magenta, or whatever. 

I'd be grateful for any advice.  Thank you.
