    True, Clive...I have heard that it can be an issue with some Foma and Efke films to not use a hardening fix due to their relatively soft emulsions...

    Though Ilford and Kodak and Fuji say hardener is not necessary, and in fact can impede your washing regimen. I haven't used hardening fixer in my own darkroom for years, and have found that the only severe scratches I have incurred on any of my negatives have been the result of grit on the pressure plates/rollers in my cameras which I daresay a hardener in my fix would have done little to prevent.

    It is worth trying a non-hardening fixer, like Ilford Hypam or the like (I use Kodak C-41 fix for both b/w film and prints, it's non-hardening and neutral ph).

    If you haven't had issues with scratches prior to now, you'll probably be fine.

    Edit: I too have also noticed that Agfa APX films are a bit more bowed than my Kodak and Ilford films...especially the APX25, though it flattens out reasonably after being in the sleeve for a day or two.

    I simply dry my negatives as long as overnight and then put them inside negative sleeves with a heavy book on top for one day. It really works for me.

    I cut them after they've dried, then I more or less force them into my plastic-sleeves, no matter how curly they may be.
    After a few days in my negative folder, they are flat.

    The only film that I've not been able to flatten after a while in the sleeves, is Rollei ortho 25. This film is still pretty curly, even after 8 months of flat storage in the negative filder. Curls up like spring. Actually, the whole "page" holding the negatives like to bend and buckle as I browse =)

    - It's just as potent today as it was when I developed it, really strange.

    Hang them to dry; put them in a sleeve; roll the sleeve against the curl and place inside of a paper towel roll for a while, overnight ideally. Totally flat when they come out. I have been doing it this way for years.

    Thanks,
    As you describe it seems to be the easiest and fastest way.

    It's always directly tied to humidity. All flattening is temporary if the emulsion is naturally curly as the emulsion will always pull against the base creating the curl.
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.

    Even if temporary, it is much better to handle flat negatives than curly.
