Response to PMK: is an after-fix bath in used developer needed if alkaline fix is used?

After using PMK Pyro now for several weeks, my preliminary conclusions are that both Ilford Delta 100 and Pan F+ seem to respond extremely well. TMax100 much less so ; I think that Rodinal 1:50 is a better bet than PMK for this film. Delta 100 in PMK and TMax 100 in Rodinal 1:50 seem to me to give very similar end results - exceptionally sharp, quite dense negatives, with a long tonal scale.

I have given up using an acetic acid stop bath with PMK, and simply rinse in water for about 1 minute, as I suspect that the stop bath did cause some pinholes. I then fix in Ilford Hypam, and so far have always reimmersed the film in the used developer. I might stop doing this with Pan F+, as the normal development seems to induce a deep stain anyway.

I would be interested in your results with Plus-X and Tri-X. Overall, I have found Mr Hutching's times and film speeds to be about right for "N" development, but some way off for +/-, particularly when combined with long exposure times.
