This was my last update, but now I have even more news. While all the above is still true I was still getting an occasional streak on a roll every once in a while. I now no longer get any streaks on Ilford 120 films. The key is that now when I add 5 drops of photo-flo to the distilled water I swirl it around with a finger to mix it up. I truly believe that this, along with just using too much photo-flo is what my problem was.
