Hanman speaks the truth regarding the raps down the Ho.
I don't know why you would do the Blueberry
route if you are a 5.10 slab climber.
Although it is fun.
Westward Ho route is way fun and you would be lined up for the raps. I would reccommend going farther than the 4 pitches and continue to the tree on the ridge. The view over the other side is sweet.
If you can ball up more than I, which should not be too hard you can make the final 1/2 pitch to the top proper.
