His 2 DVD set about building the golf swing is excellent. IMHO(often wrong though), the best way to build one's golf swing is through the shortest motion ala TGM's 12-5-1- and 12-5-2, chipping and pitching. Hebron does just that. Doen't directly use TGM lingo, but talks about it's main points in everyday language such as lag pressure points, power accumulators and generators ,being on plane, etc. Best beginning instructional DVD i've seen.
Not exactly sure what he teaches intermediates and advanced students though. Based on a book he wrote 10 years after he produced the video, he says he teaches a cross-lateral hip slide to start the downswing. He might be teaching hitting, but not enough other details were given in the book.
