Probably depends if you are going faster or slower than the tailwind. A 25mph tailwind you are probably going over 30mph, so aero helps. A 50mph tailwind you are probably going less than 50 so sail up.
That's what I was wondering.
If the tailwind is less than your speed I figured you should stay aero but if greater than your speed sit up but I'm just an amateur and wasn't sure.
