I love Power 3's. Love love love them. I loved them before I could do them, because there was just something cool about them. So, I made an effort to teach myself how to do them, and it was pretty terrible for the first few months. I'd fling myself into the turn, because that was the only way I knew how to do it, then pull into a backwards crossover, hitch up on my toepick in a straight line instead of an arc, and grind myself to a halt before widestepping into a fresh flat to wing into another turn. Anyone on the rink with me would know I was trying Power 3's by the rythmic **Scraaaaaatch**Clunk**scraaaatch**clunk** I made as I traveled.
But I didn't give up on them. Eventually I figured out that back edge, and how to hold and turn closer to the center of the lobe. I still scratch a bit, the left side still wings too fast, and my step into the new lobe is wider than it should be, but my Power 3's are one of the things I'm most proud of. I do them alternating now, along with alternating power mohawks, as a part of my warmup. I have a long ways to go on them, but they are one of the elements that shows just how far I've come.
My current "That is so cool but I can't do it" Skill is Backwards Cross Strokes. I'm sure that eventually I will do backwards cross strokes with proficiency, and remembering just how hard those Power 3's were makes the process a little easier. And enjoying the challenging Process is what makes this fun.
