Wish I could give you some good advice but I have only tested JandC Classic 200 film with the 2:2:100 dilution of Pyrocat-HD and at this dilution Pyrocat-HD is much too energetic for SBRs of greater than 8.
I could interpret from my data and conclude with some confidence that for silver gelatin printing you could handle a SBR of 8 with the 1:1:100 dilution, at a development time of about four minutes. But beyond that I won't speculate.
However, if I were working with these kinds of high contrast scenes I would dilute the developer even more, say to 0.5:0.5:100, and run some on-site tests. And two side benefits of further dilution would be even greater acutance and slightly greater effective film speed.
