If you want negatives which print easily and correctly using Pt/Pd or salted paper, you need a film which will readily expand. Tri-X 320 is not one of these, in fact in my experience it is the poorest choice one could make. The best film I find today for such development is Ilford FP4+.
Pyrocat HD at 3+2+100 produces beautiful negatives for the printing processes needing a longer scale such as Pt/Pd. Salt prints require the longest scale negative of all the processes and thus I urge students to make negatives for the Pd process first.
You mentioned VanDyke Brown prints also. These do not require such a long scale and many people make nice negatives for them with the faster films such as Tri-X and HP5+.
