Lessons will help pretty much every other skier, and I am sure they would help me. I've been in a few clinics, but no lessons since the straight ski era.
Let me give you my perspective on what I am seeing, and tell me if you agree.
Background- there was about 20" down the day the video was shot. My wife (camerawoman) is a developing skier that had injury problems last year and didn't spend much time on the snow. This was one of the few times this year I got her off the groom. Up until this point that day, we had been skiing ungroomed beginner terrain- stuff that had so much snow that it was "skied" by weighting all the way back to keep the tips up to conserve momentum-no turns. Its what my wife wanted to ski to get comfortable in deeper snow. The pitch in the video is the first pitch requiring actual turns we had skied that day.
So here is what I see.
At the top of the run, I am skiing very, very backseat, probably from spending all day to that point skiing backseat on purpose.. The front of the ski isn't engaging, I am muscling the skis around. Upper body is going crazy trying to compensate, and because I am making pivot turns, my upper body is following the ski instead of staying squared downhill.
I realize I am in the backseat, and am able to correct around the point that I am passing between the two trees. The upper body flailing settles down, I'm facing down the hill, and I even have 1 or 2 relatively normal (comparatively) pole plants. I feel the lower part of the run is a bit more indicative of how I typically ski.
I'm pretty sure I have a decent grasp of edge release. You release the old outside edge by transferring more weight to the new outside ski when rolling the tips over, yes? In my case, it may look like I don't get this as it is really, really, really difficult for me to achieve a smooth transition because I can really sense how much weight I am shifting and how quickly I am doing it. I know this should be a smooth, measured transition (ie, don't throw all your weight on the outside ski, especially in soft snow) but the reality is that some turns I will shift too much and will sink the outside ski, sometimes I shift too little and will catch up the inside ski.
Are you seeing something different?
