With "Swallow your Karma" currently a swallow rookery, this is probably the best hard climb on River Wall, with sustained climbing up a clean face for its upper section.
A runout easy blocky start leads to a hidden bolt, then a ledge. This beginning is shared with Aurora's Diving Board. (If you don't like the runout you can maybe start on the bolted line to the right.) Follow the bolted line from here to the right, beginning with a sequency crux up a glassy face. Move right, to what is sort of an arete, and pull on thin crimps through the a 2nd crux in the steepest section to an easier finish.
2nd bolted climb as you approach River Wall.
8 bolts (if using the better left start) to a 2-bolt anchor
