I first came across Jacobs about 15 years ago, when as a young whipper snapper I was given a golf instruction video, Play Better Golf with Peter Alliss. Jacobs contributed a section to the video which was part of a BBC TV series. Unfortunately, I have only recently explored his ideas further. I was always into Leadbetter in the 1990s because he is also an outstanding instructor. However since Tiger has changed his swing through Haney, I noticed that Haney was a disciple of Jacobs. There are many other instructors such as Butch Harmon, whom Jacobs has had a profound effect on their teaching methods. I bought the DVDs for what was a bargain £11.50 plus P&P and these where retailing at £39.99 elsewhere. They are outstanding, and rather confusing players with different moves to build a swing, the focus on the flight of the ball to aid your development which was quite refreshing.
