So the long and short of it is this. Over the years I have interacted with several instructors. In general they teach and want you to use their specific technique because you came to learn from them. In my experience I try to learn what they are teaching. I always end up learning something, even if its something that does not work for me. Sometimes I change my techniques, or modify them based off of what I learned. The above vid from jerry helped me a LOT.
