That's pretty strange if you get streaks with distilled water. I myself use half strength photo flo. Are you drying it in a heated environment or is it possibly drying too quickly?

What I've found is that having copious amounts of surface water+pflo helps pull water off in more uniform fashion due to the reduced surface tension allowing the water to stream off. I don't trust small beads or snapping the film to have as positive effect because its effectively reducing that "stream factor."
