OP - I think you have mentioned using perceptol? I just developed my first roll of neopan in perceptol and like the results. Perceptol is my default developer for delta 100. Otherwise it use DDX most of the time. Except for now - I have my last batch of ID11 and am using it up on some test rolls with a new lens. Once it is depleted, I'll stick with DDX and Perceptol.
