You should feel more power from the balls of your feet. It's also a bit easier to work on that "round and round, not up and down" idea of getting the most power out of all-the-way-around the pedal stroke.

I also prefer to use a 3/4 or 6/8 tune, which makes for better balance and is more like my "alternate breathing" rhythms in swimming. ("Anyhow, I Love You" [Guy Clark] is one I *try* to do but it's kind of wrapped around itself so sometimes I almost fall off...)
