Digital BW, The Print

I consider upgrading my Piezo plugin to the new ICC software. When the piezo plugin 
performed best with my 1160 (when it did not produce microbanding, etc) I was very 
satisfied with the result. I liked the Piezo dither also compared to the dither from the 
Epson driver.

I have also experimented with MIS FS-N inks in my 1160 - with the John Woolf 
Workflow using the standard driver.
It is OK but I don't like the dither produced by the Epson driver. 

Now when I plan using the 1160 with the PiezoICC that uses the Epson driver is my 
question:

Would I get a better result with a newer printer? Cone plans releasing profiles and inks 
for Epson 2200 that prints a lot better (with a finer dither) than 1160.
