Yeah, slomo can look weird, but I don't see myself how the cmos flash frames can look better. I mean, yeah, you lose the entire frame with ccd, but it looks more natural to me to see the entire frame flash white than those half-frame flashes from cmos.

Plus, I played with a demo of a plugin for fcp that removed the flashes and did a pretty good job. Don't remember the name because it was expensive and didn't need it.
