airbells sorted, but now streaking...

Thanks to John, Scott & Charlie for your help in answering my airbell problem. Pre-rinsing plus tapping before beginning developer agitation seems to have eliminated the airbells I was getting. I now have a worse problem...MAJOR streaking of the negs, never experienced before. The streaks are parallel to the short axis of the film, mostly print as lighter [denser] streaks but also can have a darker [thinner] component to them as well. I know they are caused by the little triangular teeth which hold each sheet in its groove in the Jobo reel, as streaks and teeth line up all too perfectly. But why are they appearing now? Is my great new airbell-eliminating pre-rinse swelling the emulsion and making it too sensitive to the developer before I begin initial agitation? As this is occurring on 4 - 6 sheets of film per tank [thus bringing me to a complete halt until I sort it out] and since due to finances I'm stuck with hand processing in a tank for now, I would be very grateful for any clues. thanks in advance rebecca
