Let us know how you make out with it. I've considered buying on of these for 3 years but, like you, have no idea how to use it. Everyone just says, "You don't need it." I've done at least 15 top ends since I started messing with these skis a few years ago. I guess I don't need it but it would be nice if it works.
Question - Do you have to buy a specific size for each wrist pin size? I see sizes on these things which further confuses me.
