Good luck with your project. I used Pyrocat-MC for a couple of years, at the same time as a friend of mine was doing Pyrocat-HD. Different films, Tri-X, FP4+, TMY-2, Neopan 400. We were both very happy with it, and both arrived at agitation every three minutes.
Then, at almost the same time, we both encountered problems with uneven development. He ended up with TMax and I went with Xtol and Edwal 12. He has recently revisited Pyrocat, but with rotary development. A little bit less acutance, but nice negatives that seem to print very well.
For me, I never went back, because I didn't find that much of an improvement in acutance or sharpness, not enough to matter. The replenished Xtol is mighty sharp, and doesn't suffer from the weird highlight tonality that I get from extreme minimal agitation. But you may shoot subject matter that's a little different and it is more noticeable.
I think you can probably have some good luck with it. All I'm saying is that if you get unevenly developed negatives, don't be surprised. It may never happen to you, but I think it's fair to let you know there is a distinct possibility of it.
