Reworked this article where I presented tips from catfish guide Denny Halgren on dealing with light biting flatheads and flathead catfishing in general. While it's a bit long and wandering, I think there's a lot of good tips in there.
I've been doing better the last several years letting the rod load-up in the holder (rather than "spooling" fish as Denny calls it), but I still rarely use a clicker. I still fish the single knot slip-sinker rig a lot, although I'll use a swivel sometimes as well.
