I decided to go with a hitch mount option. After 3 months of use, I think it was the right way to go. It comes with a ski attachment that drops into the bike rack. It takes about a minute to put on and take off, so I can remove it during the week. It doesn't rob me of gas mileage. It doesn't mess up the nice curve of the roof line. Finally, i know with a roof rack I would drop something on the top eventually.
