Digital BW, The Print

I've been up and running with QTR on a 9600 Ultrachrome for a few weeks 
now.  I like the CoolSe curve for many pics.  But I still haven't been able to 
come up with a blend yet that I consider "neutral."  I'd appreciate it if people 
could share what blending settings people are using for neutral printing.  I 
realize this may be different depending on the tone of the paper you're 
printing on -- I've been printing mostly on Premier Art and Photo Rag -- so if 
you could specify, e.g., "85% CoolSe blended with %15 Warm on Photo Rag, 
75% Cool with 25% Warm on Enhanced matte", that would be helpful.

Also, have people come up with "canned" QTR ultrachrome 9600 curves for 
neutral printing that I could download?  The supplied ones are CoolSe, Cool 
and Warm, but no "neutral."  Thanks!

Oh, and any updates on when and if QTR will support the Epson 4000?
