As you may have seen from the "Pyro and FP4" thread I have had similar questions to Nige in regards to the 'finished' results from a PyroNeg.

I have found the info in the articles by Sandy King and abundant APUG posts invaluable and they have been a catalyst to actually trial Pyrocat-HD but what I would find extremely useful would be some kind of visual reference as to what to expect and the differences to non-Pyro negs. This would be the groundings of a great APUG article. Any takers?
