I don't understand why some people want to say negative things about a man that has helped so many people to learn how to shoot pool better. Why not give the man credit for taking the time to teach people,whether u agree with his system, or not.He has taken the time to teach people for the pleasure of teaching his methods. I also think no one has the right to pass on his system without his ok.When the man taught certain people for free, then they teach it to students then charge them to learn it.If its not yours to give u should'nt charge people to learn it.Thats disrespect to your teacher.
