Response to Isopropyl rinse

Wait, I didn't get that. Alcohol is surely evaporating faster than water, but since you have a large amount of water in your solution, how does the presence of alcohol in it change the rate of the water's evaporation ? I would guess that the alcohol would evaporate first and then it would leave the water on the film evaporate in its own (normal) time. There might be some other angle that I can't imagine, and I would be grateful to know about it. As for Photo-flo, it is effective in reducing the amount of water that stays on the film as you hang it, since it is altering its surface tension and therefore diminishes its ability to "stick" on a surface and form drops. If used in the right way, Photo-flo does a very good job.
