I see your point about the shoulders back @LeonL if both arms are extended in the turn. But with elbows in and handle low in the turn, I don’t think it’s as much of a factor and the handle is closer to where it needs to be for the pull. Not sure it “develops” good form, but it’s one more thing to go wrong that he’s thinking about that’s not really needed @15 off. I probably should have not said it helps with form, although staying connected will never hurt. I’m still initially gliding around the ball with no load on the line so keeping my “up course” shoulder back isn’t an issue, and it helps keep my shoulders square to the boat for the pull. Good form and technique is the key at any speed and any length. Staying connected, elbows in and low, chest up, ankles flexed forward and all the rest is what’s important. More speed and a shorter line will come. But you must start with the fundamentals, and a slow speed will help with finding your balance on the ski and allows more time for the proper form in the course. As a new course skier who really sucked at it I found an outstanding coach who helped me a great deal. What I’m sharing is mostly his advice, and it worked very well for me. I still suck @ course skiing but it’s getting better. Went from 1.5 to a full course @ 15 off. Working at making every pass comfortably before bumping the speed up. Just my experience so far...back to lurking!
