Now that's the kind of post I like to see.

Regarding your concern about FD, have you tried just setting full=true? This forces every frame to be deinterlaced, but only the combed areas of each frame will be touched. Your on/off problem I expect comes from using full=false and a poor threshold.
To get the equivalent of full=true for Telecide's postprocessing, you can set post=true and threshold=0, or just use the override file to force deinterlacing of all the frames (using a frame range specifier).
The problem with blendfields() is that it affects the entire picture, including noncombed areas.
