I've gotta try it! I'm using Agfa mammography film and I agree that it's a good film. I also had trouble with some mottled development and maybe the anti-halation dye was my trouble...

I haven't fooled around with it much more than the 2 instances, though I got a nice enlarged negative by enlarging a b&w positive onto the film and developing it in HC-110, dil B.

cheers!
