Just so you understand I didn't switch from a Kodak film to APX. I haven't used Kodak films since the 70's. Had a big beef with them then and well I have a long memory. Before APX it was Ilford products. Still use a bit of FP4 for Pyro-Cat stuff. Haven't tried APX in Pyro yet but will do so soon.
I only hope Kodak stays in the B&W film business because they keep everyone else honest. Even if they themselves can't do the same.
