...My observations based on the above:
1 - ATL has so many 88 flights in and out and is such a big hub that you end up doing a lot of "little" trips that as a commuter, aren't really fun. I always hated sitting short call with one day available and get called to DH to BHM then fly in to ATL.
2 - CVG is such a small base with little mainline (let alone 88 flying) that they can't use you in the capacity that I described above. Plus I work weekdays on RSV so there are generally less sick calls to cover (guess that's why I've flown 40 hours this summer)...

Really helpful information guys, thanks so much. MSP is actually the easiest commute for me from the west coast, and I know the midwestern peeps are cool, tho frozen. There's a lot to learn, especially if you might have to choose up front... Looking forward to the work.
