Ian, remember that lengthy thread with PE a while back? With controlled temperature shocks up to +/-10C at various processing stages, I could not get this to happen at all with TMX, TMY, Tri-X, FP4, Delta, even Neopan 400 which was supposed to be most prone.
How could we forget
I'll say this, I never cared for the grain in the first TMY's in D76 straight.
I mostly go 1:1 now so maybe it wouldn't be so offensive.
