Ok, I settled on the MotionFlow preset of "Smooth". They have Smooth and Standard (600 lines of motion rez) that are just levels of frame creation, True Cinema (simple 5:5 for 24hz sources) and Custom (adjust black frame insertion and frame creation separate), which can be toyed with without changing the calibration. "Clear", which is BFI and FC causes massive adjustment to light output and a peak of 35 footlamberts, is a no go.
To me, Smooth just doubles the native 300 lines of motion rez and doesnt give a soapy look on 1080i/p 60hz. It looks a little smooth, but I like a little of it. I will try and test some 24p, and if it looks too soapy, Ill just use True Cinema when I swap to a 24hz source. I can go from Off, to Smooth, to True Cinema without affecting anything Chad did, so that is nice.
Using test patterns on Spears and Munsil 2, I can see where "Smooth" has any more artifacts (minimal) than "Clear" had, and even though Clear has 1200 lines of motion rez according to reviews, I can't see a difference in detail on the pattern that has 3 levels of scrolling text at 3 different speeds. Both make the slowest one very clear, the middle one almost clear, and the fastest "better" than off. In True Cinema mode, all of those scrolling text lines have the normal film judder/double imaging you would expect.
