Digital BW, The Print

Paul;

I've been reading this thread with great interest.  Thank you for 
all your hard work and sharing it with us.  Pardon me for what is 
probably a newbie question:

Assuming you get the UT inks dialed in with the 2200, will it be 
practical to swap cartridge sets out between the Epson UC inkset and 
the MIS UT inkset on the same printer?  I'd like to avoid dedicating 
a printer to B&W for now, knowing I will sacrifice some ink when 
swapping ink sets.

Regards;
Steve
