John,

Find the media type that produces the best dmax. Make a 100% black patch in photoshop  
and print out using all media types labeling each one as you go. Let all dry and read to 
find the deepest black. 

The above might find the best d-max but this could lead to blocked shadows that no 
profiler can fix as some Epson media types lay down too much ink in the shadows. But 
with all gray inks it might not be a problem.

Best,

John V
