Wow....heavy stuff. I'm far from an expert but I tend to retard my float a bit when the tailout gets shallow. That seems to keep the jig from hanging up most often. When your jig is bumping along the bottom it is generally upstream of the float, so the hook is pointed downstream. I lose a lot more fish when my jig is bass-ackwards, so I don't even cast upstream very much for the same reason. However, when I fish bait below the float I'll sometimes let the weight, usually a slinky, bump along the bottom just like a drift rig. Seems to work OK.

I use 20 or 30 pound hi-vis Power-Pro, so I always employ a leader of good old Maxima.
