Hi! Just 2 quick questions in preparation for my 1st Whitney climb next month.

1. Best leaving time from trailhead. Sunrise on Sep 21 will be 545am, I'd like to have a little bit of light when I reach the ledge, I'm pretty much not affected by elevation until 12k feet, fit hiker. So when should I leave the Whitney trailhead?

2. Best return route. I have never been on Whitney but I do want to return to the trailhead quicker. What's the time difference between a descent on Whitney trail and MR trail?

Thanks! I've been watching the videos every week and printed out pretty much all the trail pictures for an easy route finding.
