I'll always take the tailwind when I can get it. Who knows - it might switch for the way back and I'll have tailwind for the entire ride! (Yes, it's happened before.) But generally, wind doesn't bother me as much as others, so I don't worry about it like I used to when I rode uprights. And anywhoo... the trick isn't to schedule so the trip home is the easy leg ('cuz it might not be,) but to allow sufficient time for a headwind.
