Digital BW, The Print

I want to get a boost in DMax from dye inks with the Piezo's dot-less 
hightlights. I'm thinking of mixing a home-brew, "enhanced" black 
using  pigment blacks and dye blacks. I have a bunch of various MIS 
inks to mess with.  Any suggestions?  The dye is not as permanent  as 
the pigment but will be fine for mounted, framed prints.  

thanks,

AZ
