I'm no expert (developed something like 15 rolls of film now), but my personal experience has been that there will always be some drying/runoff marks - no difference if I used wetting agent or rubber drier blade.

I noticed that the matte emulsion side usually is fine. The marks are visible on the shiny backing. So i just breath on the film strips a bit and clean the marks with microfibre cloth. If needed.

Are the marks whitish? Are you sure that all your darkroom water is not calcium hard?  Have you tested your water hardness? I can see if you have very hard water in the darkroom calcium residue may be difficult to avoid. It could be pervasive. I only used filtered and soften house tap water in all the water needs in my darkroom for mixing chemicals and washing and used Kodak Photo-Flo 200 according to instructions and never had any spotty drying problems.
