Your message suggests a printing difference of four grades, i.e. #1 for graded papers and #5 for VC papers. That does not sound right to me. I have never observed a difference of more than two grades with any of the pyre staining developers, and typically the difference has been less than a full grade.
I agree completely, Pyrocat-HD does indeed do well with all papers. But with my LF enlarger with hand-held contrast filters (I use Yellow and Blue), it is a little frustrating...

The difference in grade I reported isn't exact - as I said just now I use "split grade" printing. But the difference is certainly a lot more than one grade! Maybe I'm overdeveloping? Or maybe my lightbulb is too yellow?
