    Thanks ic-racer. My next step is to test slower rotation speeds to see whether that allows the chemicals to penetrate the back side of the film better. Just hoping I don't get streaking from under-agitation. But I figure the only way to find out is to try.

    Possibly the easiest step is to put the negs in a tray of hypo clear after fixing to allow the backside to clean up. Then do your wash in the tray.

    Yes, if the speed reduction doesn't work that'll have to be it. But now that I know the issue is solvable, I can experiment without worrying about losing images, so that's great in itself.

    Have you tried a pre wash with water prior to development? I use the JOBO test print drum (forget the number) to process 4x5 negatives with no problems. Just a thought that a 5 minute pre wash swells the emulsion and allows the developer to work more evenly across the sheet when first introduced to the drum.
