For starters I would tell you to take control of the pedal. Because if you don't control the pedal, the pedal will control you. With practice, you have to figure how to make it stop when you want it to stop, and go when you want it to go. This is way more impressive than doing doubles and triples. There was a day when I couldn't even get through a song without throwing in some doubles. I was just fascinated by them. But now I hardly ever do them. Control is the key to the best footwork I've ever seen.
