Digital BW, The Print

"The 2200 plug-in seems to be priced very well for people looking for 
a dedicated B&W solution on the 2200...."

Are we assuming that changing inks between the OEM Ultrachromes and 
that Septones will be impractical/impossible?  I'm intrigued by the 
Septones, but definitely will want to switch back and forth.  I 
realize this will waste ink b/c I have to run cleaning cycles when 
switching, so I won't be swtiching on a daily basis.  I'll probably 
just print all of my current at any given time b&w images, then print 
all the color ones.  But the guy I emailed at inkjetgoodies indicated 
that switching back and forth is certainly feasible.  Anyone else 
have thoughts on this?
