angels crest - i'd only say about 3 pitches are 10a (angel crack, the #4 moving up the corner and out right, and the second-last), plus the bolted 10b and then the 10b var to the 5.8 whaleback which is where you can pass all the slow parties.
but make no mistake, its easier to do squamish buttress than angels crest, nowhere near as sustained and the crux is short, super well protected, and you can french free it easily. also usually done much faster, like 4 hrs vs 7 for angels crest
doing linkup of both in a day is good practice for long alpine routes!
