I just ordered Duke Roufus' Muay Thai Instructional DVD. I noticed that his instructional was usually listed as one of the best. However, I am interested in learning real Muay Thai as it would be practiced in Thailand. I also bought a clinch DVD that is often the number one suggested resource on Sherdog to supplement it. Should Duke's DVD give a good enough presentation of Muay Thai? If not, what would be the differences?
