Digital BW, The Print

While I am very pleased with the capabilities of ABW printing with the
Epson 2400, I miss the control over tonality I had with Paul Roark's
inksets -- the ability to vary the tone from cool to carbon as I
recall.  To this point, I have aimed for neutrality, making only the
minimal adjustments Clayton Jones recommends to account for variations
in papers.  Thus a question:  if I make the larger adjustment needed
to produce a warm print, for example, how much color is inserted into
the print and how much of a problem would that be?  When I set the
driver to "warm," the print was not all that warm and I could not tell
whether color inks had been added. Am I better off sticking with
neutral prints with the ABW driver?  I have not tried to make profiles.
