Digital BW, The Print

The Christmas Crazies have left me even more confused (and behind) 
than usual. But I think I remember that I could use an Epson 1160 
driver with some of Paul's curves, the MIS VM inkset, and  EAM or 
Museo. And that I could instead buy the PiezoBW driver and use it 
with the MIS FSQ inkset on EAM or Museo.

However I have the impression that to use the PiezoBW driver 
successfully, you have to have a printer which can be aligned, and 
kept aligned, precisely (eliminating some fraction of the 1160s), 
whereas the Epson driver is more tolerant in this regard. Is that 
correct - that the PiezoBW driver is more punishing for any shortfall 
on the alignment?

I also have the impression, though, that the PiezoBW driver is 
faster, at least on the 1280/90. Is it on the 1160?

And that there are preview advantages in Photoshop 6 from using the 
PiezoBW software. Is that correct?

If the Piezo software is faster and easier to use on the 1160, I 
might spring for it and order the FSQ inkset (and a CIS). Otherwise, 
I think I'll order the VM (and a CIS). Especially since I intend to 
later use the sepia-neutral inkset Paul has been developing for (I 
believe) an Epson driver. In fact, if the sepia-neutral inkset is 
accessible, I'll order it now instead of either FSQ or VM.
