Digital BW, The Print

I am using UT2 Ultratone (from MIS) with my Epson 1280 with marginal 
results.  I never obtain a satisfactory neutral print. It seems too 
cool for my taste with a slight magenda cast.  I have been using 
Paul Roark workflow and curves with matte paper. I have not been 
succesful in modifying the curve to get a warmer result.  I was 
trying to go somewhere in between neutral and carbon but it does 
become brownish AND magenta at the same time !!  Anyone can propose 
a curve that works well ?

Paper: I am using Epson Matte Heavyweight, however the curve is made 
for Epson Enhanced Matte.  Does it make a big difference ?  Anyone 
has compared result for both paper? Is it the source of my problem ?

I am not interested in warm, sepia or anyting like that.  What I 
want is a straight neutral print that would look like a traditional 
darkroom print.  Should I switch to monochrome inks (like FSN from 
MIS)?  Anyone has experience comparing UT2 with FSN ?

Thanks for your help,

Michel
