Dee, is it possible that you mean The Science of Motion and Jean-Luc Cornille (not sure I spelled it right)? If you are, I have the exact same opinion, all of the articles I've read from him are very eye-opening, but I don't really like the fact that he is indeed very traditional. And he is quite mysterious as well, regarding his methods. I am very curious about his course, but I get the sense that one would have to be a far better rider than I am, to really benefit from this course. Maybe sometime in the future...
In the Equine Sciences Academy there are no courses involving tack, so that's why I thought that you mean The Science of Motion. I'm sorry if I understood wrong
