I used Don's PPPD developer this last week with very good results. It was a bit too contrasty for my Azo negatives, but printed (enlarged from 6x6) with excellent results on some 10+ yr old Oriental New Seagul Select VCFB paper that I have. I have a negative of mine that would always blow the highlights out on paper(with Ansco 130 or Neutol WA), and with this developer I was able to get detail back in them, as well as a wonderful depth to the photograph. In order to cut the contrast down for Azo, I'll be leaving the pyro out and just go with straight catechol. I still love Ansco 130 both for its tonality and its VERY long shelf life, but I imagine I'll use the PPPD for final enlarged prints. For final Azo prints I plan on using Michael's Amidol formula. I still havn't tried it yet because I don't have enough prints to run through it in order to make the high price worth it....can't mix it up and only put out 5 prints....
