Homer wrote his original book in 1969 (40-years ago). Although TGM is based on the laws of physics and circular dynamics, there have been many changes to the equipment. Metal drivers were introduced in the late 70s early 80s I believe. I think the first metal wood win was with a Taylor Made (could be wrong though). Today's exotic metals with unique characteristics are the norm. Every manufacturer has there "spin" on why their design is better but they all have one thing in common. Manufacturers have designed these heads to minimize spin and therefore increase distance. To minimize spin the ball must be hit on the upswing and the contact point (sweet spot) is above the center of the face. If anyone has been fitted for a driver with a launch monitor, the data speaks for itself. Last year I went to Callaway's performance center here in my home town and was fitted for their FT-5 driver. I took several swings with my existing Big Bertha and was told that I had a negative attack angle and was getting too much backspin on the ball. I said that's the way I have always hit my irons and they said that is what I am supposed to do with irons. However with a driver, the manufacturers want you to have a positive attack angle to decrease spin and increase distance. Could the new technology of the driver face warrant a different ball position? Would luv to hear from a club manufacturer on this one.
