Just curious, but I've read the Unblinking Eye article on Azo + Amidol, and it's curve doesn't look radically different from the Ansco 120/130 curves. According to "The Print", those are closeish (give or take an ish) to Selectol Soft from the Yellow Peril.

So..., what are people's opinions on Selectol-soft + Azo, rather than the pricier and less stable Amidol?
