Andy I love your book and have learned a lot from reading it. I am still pretty new to the CTX 30/30 I think you should do in instruction videos or a DVD that people can purchase to help them understand your book more. I would love to make it to one of you classes I am from NY and it would be a heck of a trip to get to one. So for people like me a DVD would be perfect explaining the stuff in your CTX 30/30 book. I don't understand the pitch hold feature and how it works can you explain that to me? That would be much appreciated
