In my case and practice the development of the negs in Pyrocat HD adds even more to the desirability of using the Ilford 500 controller as a split-grade unit, for which it is particularly suitable, and I've used that technique for D76 developed negs too.
This helps me with each paper's characteristics.
I use Ilford RC matt, and FB glossy and semi-matt standard tone and warmtone.
This may not be the answer that you are seeking (not uncommon on this forum!) but I hope it helps.
