Piedmont shouldn't even be an option these days.

I drive to work at PDT. 4 on 2 off, at 75 hours credit is life.
Just a few years ago the flow time was realistically attractive, and premium pay made up for the schedules. Those things won't be here for you now.

Republic sounds like the best bet in PHL today. Unless having a 9.5 year flow date "in your back pocket" is something you really think you'll need.
