I squeegee film my fingers as I always do for 120. I don't do it with 35mm because I've had issues with water spots. But up until now I have never had these issues with 120. Squeegee streaks as I have seen them are on the base of the film and can be wiped off. These see to be in the emulsion. Agitation seems likely but I used the same agitation as always. I do rap the tank on the counter and use the recommended amount of developer.
I should mention that I recenlty swithched from Photo-Flo to the Edwal wetting agent. Photo-Flo sposts my 35mm film no matter what I do to it.
