Hi
I certainly haven't done exhaustive testing, but pyro stains may be scanner dependent (I normally use the green channel if the software doesn't pick that). I quite liked what it did when I was printing on an enlarger.
Pyro is great for enlarger based processes. My scanner doesn't care about Pyro staining, it isn't blue sensitive in the same way that darkroom paper is. The biggest problem I came up with was very flat midtones. There are many versions of Pyro and while PMK is one of the best, IMO, for developing in a tray (I didn't test BTZS tubes), it doesn't work well, or let's just say I didn't get it to work well in a drum - especially with TGrained films.
When I run out of (or perhaps just before I run out of) my current batch of D-76.
D-76 came out a bit grainier than Xtol in my most recent testing... enough for use to dismiss it.
