Digital BW, The Print

This question may have already been addressed previously, but I am
new 
to the B&W digital print process, having just invested in the 
piezography system.
Is it possible to print with the MIS FS inks using the Cone plug-in
and 
their paper profiles? If so, how accurate do the profiles remain with 
that ink/paper combinations?
I have just tested about 10 different papers  using the Cone profiles 
and was impressed with their consistency- there was very little 
adjustment required when changing the papers other than nozzle 
alignment for thickness. I'd hate to lose this functionality, but I 
need to convert now to a CIS system, and Cone is seriously expensive, 
and causing me some problems as well. 
I seem to be experiencing the dread clogs, and although the nozzle 
check prints out with no gaps whatever, I see very fine banding in
the 
dark midtones through to the blacks. This banding was not occuring
for 
the first week or so after I converted my 1200 to the system, but
after 
leaving the printer unused over the Xmas holidays, I got the bands. 
Nothing I do gets me back to the original state (I've tried all the 
cleaning 
tricks) and am hoping that a change of inks will do the trick.
I've seen what the system is capable of, and want desperately to
retire 
my wet-room, but I'm just not yet producing the quality that I need
in 
order to do so. 
I've made labs redo giclees because of technical problems with 
their prints, and I don't want to be put in that same position where
my 
clients do the same to me.
Thanks in advance for your comments.
