This is my neighborhood (one of them, anyway) and that is what I would do. It minimizes the time crossing the rocks. Once you intercept 50 westbound, its all downhill fairly rapidly to Placerville. Stay on the updraft side of the passes if there is enough wind to promote updraft/downdraft.
If the winds aloft in the KTVL area are more than 20-30 at 9,000-12,000', I would wait for another day.
