Phantom Staircase Middle 

Stay to the left, near and almost over the corner. The phantom left staircase is on the other-side of this corner. It is tough to tell this from guidebooks and drawings, but after climbing this route, it becomes more obvious where the routes must go in order to maintain their appropriate rating. This is a good route to do, if it starts to get too tough, then traverse left where the holds become slightly more positive. If you feel you want more of a challenge, traverse right where the holds begin to become more non-existent.
