Not exactly the hardest 5.10d in the valley but a good ol pure O.W. to be sure. Good feet out on the face give many opportunities for rests and several good holds inside the crack make the climbing much easier and faster.
One Black Diamond #6, #5 and #4 is all you'll need to get yourself to the top.
The topout is a fabulous grassy patch, so be sure to make the second haul up the wine and cheese.
