The hardest moves on the whole route may actually me the openning boulder problem moving to and off of a tinny 2 finger ear. Of course this says nothing about the sustained nature of the route with few "easy" moves and really only one rest down low with a knee bar in the shallow right facing corner. For more specific beta watch any number of videos.
One of the most repeated 9a+'s in the world but also one of the oldest.
