Digital BW, The Print

I'm considering following Clayton Jones' recommendation for Moab 
Kayenta paper. I am using an Epson Silver 1280 with MIS inks 
and QTR. QTR does not have a curve for that printer-paper 
combination. Would it differ significantly from those given, i.e., 
Epson EEM, Hahnemuhle Photo Rag and William Turner? I'm not 
terribly enthusiastic about generating my own curve, inasmuch as I 
don't have a densitometer.

 Suggestions would be most appreciated and helpful.
