Sorry. Can't help there. I use HP5 or T-Mx 400 and Rollo Pyro in a Jobo CPP-2. There is no grain that you can see in 7x17 contact prints. I have read that Neopan Acros has much better reciprocity characteristics that HP 5 or FP 4, but it is not available in the size I shoot, so I have no personal experience.
