Rocky Joe, I agree with Ivan, not only is that a long day, but why do it twice like that?
If it were me, and it may be me this year, I would start at Pole Creek TH and do North, Middle, South, Broken Top and if you're crazy, like like these cats , Bachelor. Then car shuttle back to Pole Creek. They did it in 15 hrs. That would be a little fast for me though.
