as 3/4 swing with the Robertson Grip. All the testimonials you see on the web site are on his first instruction video, there's a total of three video tapes very well produced. Scotty told me that he isn't double jointed or triple jointed as you say. I have no idea how he can do a John Daly swing using his grip. If I ever get out to Arizona I'm going to see him just to watch him swing. I have talked to his clubmaker which only makes his drivers, he said Scotty breaks drivers due to his club head speed.
