moving downstream, jump up onto a rock and do a 180 or a 540, pref a 5 of course, as your bow comes back upstream, slice it into the water to make it a bow splat, keep wheeling, preferrably in the opposite direction you were moving, come away from the rock on your stern, use the eddy water to rotate around your long axis (screw around) until you get back into the right alignment to do some eddy-line wheels until you run out of river power, no sloppy throw downs allowed, this is to be done with as much of the rivers energy as can be harnessed

.. deck grabs anywhere in this sequence award huge style points
this ones old, but a rocket-move reentry is super stylin, especially if you can move straight into an aerial once the wave is caught, i have definately never landed that
in a hole, 360 stern twist into a back loop, i have definately never landed that either
