This is sort of like asking what seat should you put on your bike. It's a very personal choice. We're pretty flat here in Lincoln Ne and 53/39 with a 12-27 works well here for me. If I did any serious climbing, I'd probably want a triple (not really a climber) but would give a compact a try for sure. I'm pretty sure I'd appreciate a compact if I road in Omaha as it gets hilly there.
