Brian this is only my opnion and I am sure many will disagree with me, but I would venture to say that just about any high acutance developer would be good for contact printing.
I use ABC pyro and have increased the sulfite just enough so that I get minimal stain, the effect is such than my highlights get the benefit of the pyro stain but just barely and the rest of the negative looks almost like one developed in a regular developer. With TMY 400 I get almost no b+f and very nice deep shadows....but then I have tailored this for printing in pt. Maybe for azo it is not such a good idea.....When I moved to Mexico I had no access to all the chemicals so I used HC110 dilution B at 1:30 and got very nice might want to try this.
