Kev, I'll give it a try but I'd like to know is the addition of EDTA specifically for this issue or just some wider aspect of rotary processing?
I use pmk +edta for all formats in my jobo. No streaks but I'm using expert drums (speed 4, 1000ml in 3005 & 500ml 3010 tanks) for sheet film. I believe the edta is recommended to reduce the effects of oxidization due to constant agitation (I don't feel like digging the book of pyro out). I don't think this will reduce your streaks.
