The crux is the last 10'. It is very slabby with crimpy holds. There is no place for protection on the last 10'.
This route follows The Bone until the last 10'. At the last 10' instead of traversing right continue up the slabby face. The hand holds are crimpers. All the holds are there for an easy 5.7, you just need to look for them.
Top anchor is the same for The Bone and The Bone Variation.
