The key to learning this flip is figuring out the correct pop. The heelside back roll is a load-and-release-style invert. This means that the flip's function is dependent on line tension. To learn how the physics work, it is best to break it up into a series of small steps in a low-impact environment. "It was more trial and error for me when learning," Shawn Watson says. "First, I tried inside outs to get the rotation, then I went to a 60-foot rope length to land it and then gradually lengthened my rope out to the normal riding length."
