Hey Kent,
I was taught that leg pumping is really a by-product of hip rotation. The strength of your stroke comes from rotating your torso and using your back and stomach muscles.
It really is worth having a few lessons when you start out to the so-called "forward stroke" right.
Epic sell a pretty good DVD (although it's pretty old now) showing Greg Barton and Oscar Chalupsky demonstrating good technique.
Good luck!
Rob
