Starting below the dihedrals, climb right up the platform past the small arching overhang, then go left up the dihedral wall to a sloping ledge and then on to the top, not using the edge.
Using the edge makes it 5.9
Left hand palm, left foot on the black smear spot, and the key is the right palm on the right wall and press youself up so you can get both your feet into postion. You are not done yet. you will still have some delicate palming to standup. Work yourself up one more step to the nice flake in the middle of the left wall. Once you get the first section done, the rest is cake.
I'm not positive I did it right- I know I used the edge at least once- gonna have to go back and fix that. It's a really cool climb tho, and I would recommend it because it's not very power-hungry, just technically demanding.
