One of the swim magazines just published an article on this topic. The researcher concluded after analysis of the fastest swimmers. their arms (in freestyle) functioned more paddle like than the propeller (s-curve stuff) we were taught years ago. I didn't keep that issue, but it stuck in my mind as a different conclusion than we might expect. However if ever watched Janet Evans wind-milling her way to records that stayed unbeatable for years, I guess it makes sense.
