Digital BW, The Print

Before I stick the UT quadtone B&W MIS inks in my 2200, I just want to 
verify among the current users, that they have not encountered any 
clogging/etc problems when changing back and forth between the Epson 
pigmented color inks and the MIS  inks that are specifically for use 
with the Quadtone RIP software ( see 
http://www.inksupply.com/index.cfm?source=html/ultratone.html) ?

Although I would prefer to dedicate a printer to purely B&W, I need to 
show it really makes that much of an improvement before I can fork out 
the extra $$$ on another printer. Hence the ink switching with the 
current printer while I test things out for a few months.

Are there any precautions/extra maintenance steps I should take in 
using the  two inks in the same printer?
