I'd definitely pick Murray over best of five sets on a court that isn't remarkably fast (though, as we've seen, slower helps Sods because he has more time to set up those big swings even if it means his opponents can get more balls back).
Not that Soderling can't beat Murray, I just think Murray is too consistent over a long match. The key, IMO, would be for Soderling to win the first set. I don't see him coming back on Murray, but, again, it's certainly possible, I just don't expect it to happen.
Sods is playing well.
