Digital BW, The Print

i'm considering using the ultratone-7 inks from MIS on my epson 2200, and i'd be very 
interested to hear any experience you might have. in particular:

1. has anyone seen an ultratone-7 print and compared it to a piezography print?

2. how about Quad RIP? i've seen roy harrington's scans on the web, but i'm still curious to 
know how the overall print appears in ultratone-7 versus Quad RIP.

3. have people had head clog problems with ultratone inks?

4. do the ultratone cartidges suffer from the same reporting problem as the piezography 
ones (not reporting accurate ink levels)?

5. is it really true that you can just put in the ultratone cartridges without flushing out the 
ultrachrome inks?
