What is the purpose of the Atomic Power Control feature, and what’s the proper way to adjust it? Also, I keep seeing references to boot stiffness, but can’t find any explanation of the physical significance of the numbers or how stiff mine are (Atomic M9’s, about 5 years old).
I had been struggling to get out of the back seat and thought it might help to kick the cuff angle forward, and as far as I could tell that’s what the Power Control was intended to do. So I loosened the screws, put the boots on, put my toes against a wall and flexed my ankles so that my kneecaps also touched the wall. Then I had someone tighten the screws back down, the result being that the scale on the Power Control indicated its most forward position.
That seemed to help my posture a lot. I’m on Head Worldcup ISL’s with Tyrolia demo bindings, and I eventually discovered that moving the bindings two settings forward quickened up my turns and reduced my tendency to wash out in the back.
That was a couple of years ago, with lots of training I’ve gotten a lot better about staying forward and I now consider myself a PSIA 8 (provided I’m on groomers). My ankles have a lot more range of motion left, and as far as I can tell I’m not having any problems pressuring the front of the boots. Only thing is that when I went out west for the first time ever (Alta was great), I was having a lot of quad burn. I suspect that it was mostly due to the altitude, the vastly greater length of the runs and the fact that I've let my core go soft. But might the forward lean of the cuff have contributed? In general I’m trying to understand what happens when you vary forward lean.
