Digital BW, The Print

I can think of a way to make a qtr curve that would maximise the use of the 2% dilution as follows(think it would work?)
In addition to using a qtr-BO(for cooling/neutrality) curve and a qtr-eb6 curve one could make a third "cooling" qtr curve (also for "cooling" as you seem to suggest).  This third qtr curve would only use eboni-mk and the 2% dilution.  by increasing the ink limit of the 2% dilution sufficiently (without going overboard) one could create a curve in qtr which would maximise the use of 2%.  then, for final printing one could blend the three curves(BO, EB6, and max2%) in order to maximise smoothness while keeping tone cooler.  
I might be totally off.  have not used qtr in 3 years and am waiting for my epson 1400 along with my EB6 inks!!!  looking forward to your inks paul!
