Follow the crack straight up the big roof. There are a lot of jugs throughout this section that make the roof very manageable. Watch out for cactus at the ledge half way up. Finish by working right after gaining the big ledge, ending on the face of the giant block at the top.
Just north and around the corner from X, Y, Z, it's the thin crack that goes straight up the roof.
Standard TR set up. Long slings helpful.
Bring small stuff if you try to lead it from what I remember.
