I will jump in here and say that I have been using PMK with HP5+ for over 4 years and have just used it on 2 boxes of Classic 200. The negs look great. I am using ei 100. They have more color (green) than the HP5+. I will attempt to print some tomorrow. I don't think I will have any problems in that regard. I would try some of the Pyrocat HD but I still have so much PMK that I would hate to just leave it after it has preformed so well for me in the past. (I am more interested in images than hopping around from one developer to another developer anyway.) I don't have any issues with those that do as it makes my life easier if I can just use the info that they learn and I don't have to do all that work.
