Thin and sharp climbing down low gives way to easier climbing with thin moves spaced between several good holds along the way. Up top you can stay in the crack or make use of the arete on the right. Soft for the grade.
The book has this as 12a, most people agree that it would be 11d, the book specifies that it is soft for the grade. The crux is a 12a crux but it happens super low and once you are past that it gets easier as you go up which would explain the general consensus of 11d. It isn't sustained so you don't get exhausted as you would on many 12's. This is my first official 12a send as I've only ever 1-hung the others so if the book says 12a, soft or otherwise, I'm taking it ;)
