That is a tricky question. As you know there are so many factors in hiking/climbing times. Pictures, breaks, route finding, who you hike with if not solo, time on the peak etc... I can say that Leatherman from the east is doable and enjoyable but again that is just my opinion. Good luck on your climb. I have seen times from 4-12 hrs car to car. If you have the day and are in decent shape it'll be an enjoyable day.
