I usually run the PBSF on my seatpost/seatbag blinking and the one(s) on the rack/freeloader solid. In the summer when I ride the road or xcross bike to work and only have one rear light, I keep it on flash.
But Chip ... with your hair so free-flowing ... research shows that you should have extra passing clearance and probably no need to have a blinky. In fact, you should have a front light mounted on a rear rack pointing at the back of your head.
