Doug - I entered the Pyro realm years back via Gordon's book and B&S's chemicals. Always been pleased with the beautiful PMK negs from single-sheet tray development but if your development is 'tubular' your likely ticket is "Rollo Pyro, Pyrocat, etc. Also, the good book's guidance to post-stain for a minute or two in used developer is not necessary and no longer recommended (I found this out the hard way).
