Phil K, I think the switchbacks will be the way to go in 3 weeks. There will be some ice at the cables, but people get past it with a little caution.
Sierra Seeker: If you are coming from near sea level, the best way would be to spend your night at Outpost Camp, since it is considerably lower than Trail Camp. Then get up early and try to leave for the summit at 5 AM. The lower altitude will help keep the altitude sickness symptoms down, but you are still close enough to summit and return in one day.
