On the sharp northwest arete is a simple line that starts low and goes up and over the top, where The Bisher Traverse aka The Lightning ends.
The grade is an estimate, as I've only done it once. Worth a look if you're looking around for something to do and the testpieces are out of your league.
This problem may be easier depending on where you start but for full value, start right of the arete in the flared, dihedral feature and move up and left gaining the arete. Tricky balance moves and slopey holds. Lots of fun.
