Sounds like my approach.

Note that Edwal LFN is itself a blend.  

With respect to the detergent action, the first hint I had as to how good Edwal was came when I pulled a blend with it in up into a pipette I had used quite a bit with the Photo Flo only blend.  The pipette had a lot of carbon stuck to the sides.  When the Edwal base (C6b) was pulled into the pipette, that carbon started to fall off the walls of the pipette immediately.  I was very impressed.
