i am going to be getting some of the PyrocatHD in the mail on Monday or Tuesday. I had planned to compare it to PMK with LF film in trays first, but I will make some tests with my JOBO and 35mm. and post the results.
One suggestion would be to increase the total volume you use. I have found that doubling the volume of solution listed as minimum amount in the 1500 series tanks eliminated problems i once had with some uneven development. the same might be applicable to the tanks you use.
