Digital BW, The Print

I recently started working with VM inks and I am really happy -- so
incredibly easy compated to getting good, repeatable results with
Epson dye inks.  
Anyway, here is my question:
I love split tone prints in the wet darkroom and I could do them
reasonably well with Epson color inks.  What is the best approach with
MIS VM inks? 

Thanks -- Mark
