A nice route but I'd call it 10 C or D. Anyway, a bit run out, not too bad. Nothing to hit on a fall except the last pitch. One can hit a ledge from about 10a and 10 ft. I would be inclined to give it a R for this reason.
First pitch is a bit dirty but not bad9,(10a ish). Second pitch is really good face climbing on decent holds,(.10-) Can easily run the third and fourth pitch together with no rope drag(.10b). Pitch five is crap(5.8)
The easiest .10c you'll ever climb and uncharacteristicly soft for Cal Domes. I say .10b, but only because of the 4th pitch fingercrack.
