I just tried this today and it was interesting. You can definitely feel the very prominent arc of the rope going out and you start to learn what you need to do to make the turn and get back to the other side.
I certainly don't think I would have been able to make it out to any buoys, but just feeling the differences compared to my usual length of 28 off was educational. You have to stick with the rope (i.e. handle control) right up until you initiate your turn to go back to the other side, otherwise it's slack city.
I also started to feel that if I stuck with the rope, the release of the ski to initiate the turn was much more pronounced. It's like you're saving that energy until you need it to initiate the turn and head back to the other side quickly. Also, it works totally different muscles than the longer line lengths, but that might just me using even worse "form" than normal.
Anyway, I felt like it was kind of an eye opening experience, but I don't know that I can translate what I felt to the course. I might need to try free skiing it for a while to see if I build any muscle memory that I can take back into the course.
Not sure how to deal with a long link?
