I use PMK, not pyrocat, but have found a serious problem with the new ASA 400 Tri-X, which I use in medium format when I need to hand-hold.
The "old" Tri-X stained beautifully, almost identical to HP5+. I preferred Tri-X because I found (your mileage may vary) that, given identical subject, exposure, and development, Tri-X was a bit punchier and a bit faster.
However, the new 400 medium format Tri-X stains weirdly and I can't get the look I'm like. So I'm now using HP5+.
Obviously, the above comments apply specifically to 400 Tri-X medium format. Don't know, but I get the impression you are shooting 35mm. My guess is that whatever changed in medium format 400 Tri-X also changed in 35mm, but who knows? Also, who knows what pyrocat does with the new Tri-X? So all the above may not be worth much.
Good luck,
Paul
