This would be sweet if they actually taught the moves. But there is no teaching, just demoing. If you dont have a strong idea of how these moves work in order to gain much knowledge from these tapes (or DVDs)
From the site:
"Are the moves taught, or just demonstrated, in the GPS series?
The moves are not 'taught' in the conventional sense. There are no "put this finger there and that finger there" instructions. However, the goal of the original series was to understand the techniques in order to be able to spot them, and almost every technique is shown from angles that facilitate learning the core move. Put another way, if you were a serious golfer, do you think you could learn anything from watching almost 6 hours of Tiger Woods swinging his driver from a dozen different angles? When it's all said and done, there is a massive amount of technique, rhythm and handling touches to be learned from this series."
