Digital BW, The Print

Now that I have QTR working again, I'm interested in how I can do 
softproofing with it.  I believe I saw a post from Carl Schofield 
about that--but isn't he on a Mac? (and now I have to find that post 
and his site again)--or doesn't that make any difference.  I also saw 
that he had a profile for Hahnemuhle PHotorag.  My question is---with 
the new 2.1.13 verson and the GUI--would I use the grayspaceXYZ 
profiles and use Lou's instructions to extend the possibilities of 
Quadtone RIP?
