I would say go to Ed Wright. He is wonderful. I learned so much from him just in a few hours at his house. I have never been to any of those listed, so I can't comment on them. The only ones I have been to are Martha Josey and Ed Wright, and Ed is really advanced barrel racing 101. Martha Josey is more for the beginner to intermediate and horsemanship. They are wonderful, don't get me wrong, but if you are wanting more, then Ed wright is better.
