I use stock settings. I have and I'm currently using the larger wing at 10 degrees. This ski is sensitive to rocking back. You are rocking back a little. My greatest success is coming from staying with my ski, over my ski. It is much easier to lean back and away, than leaning away while moving with the ski. ( i believe it takes more strength to stay with the ski because you will ski with more angle) The person who does this best is Nate Smith. I haven't heard anyone really discribe this technique completly. However I know that I want to stay over my front foot, lean away, and make sure my body is moving in the direction the ski is going in, I DO NOT want to lean back at all. (That is ineffienct as the body will be going in the opposite direction of travel) I have found that if I'm on my front foot at the apex, if I have enough angle through and off the wake as I travel out bound it is much easier to have my body stay with the ski, keep my outside shoulder away from boat as I move out, stay over front foot at apex, reach and allow my self to ski into the handle, bend ankles/knees as 2nd hand comes back on to the handle, lean away and again stay with the ski as acceleration starts. This ski doesn't work as well when you push on your back foot even a little/ which you do in a subtle way. I do like stock set up 10 degrees of wing seems to pull the ski under me, which I do like. I do like how you come up over the ski coming into 1 3 5 You do push on your back foot as you gate in and 2 4. You push at the completion of 1 3 5 This ski will shoot out in front of you like it did on video 2 as you came around 1. I hope this helps, I hope I'm describing what I feel, it is a very subtle change of where your body is that will help you, I don't think its a fin blade set up issue.
