Digital BW, The Print

I have used the MIS VM ink cartridges to print to my
Epson 1280 from my Macintosh and been very happy (until
the ink ran out).  I am now considering ordering an empty
MIS CFS unit and a set of Ultra Tone inkset bottles.  I 
see there are workflow curves for the 1160.  

Are there curves yet for the Epson 1280?

If not, should I use the 1280/Mac curves?

Thanks,

Michael
