Digital BW, The Print

Sorry for cross posting - I sent this initially to the Piezo list but 
realize it may be more appropriate on this list.

Question:

I have Full Spectrum Neutral in an Epson 3000. I like the inks. I use a 
Serial (Belkin) to USB converter with Gimp Print, etc. Seems to print 
fine – although I do like the characteristics I'm reading about with 
the Piezotones.

I purchased the new Piezo ICC profiles.

I do plan to evolve to Piezotone inks as the FSN inks run dry to keep 
variables and process as simple as possible.

In the meantime, does the list think it feasible to create a profile 
that will make quality prints using Piezo ICC and FSN inks?

I work on Mac OSX with PS7.

Any advice regarding the working method/process assuming this is 
feasible?

Thanks,
Jamie Gannon
