Purtzer's four secrets to driving the ball better

FROM PGATOUR.COM
Tom Purtzer has always possessed one of the sweetest swings in professional golf. He led the US PGA Tour in driving distance in 1990, averaging 279.6 yards, and has also topped the driving distance category on the Champions (Seniors) Tour in four of the last six years.
Here are Tom tells you his secrets of how to drive the ball better:
1 Get fitted for the right equipment. Take advantage of the available technology to find out what equipment -- shaft, clubhead loft, ball -- will be of greatest benefit.
Purtzer: "The modern high-tech equipment only helps if it fits you properly. If it doesn't fit you, it's worse than using what you're using now."
2 Keep stretching. Hitting a golf ball a long way is more about flexibility than strength.
Purtzer: "To me the most important thing is to be able to stay flexible enough to make a body turn -- shoulders, hip. That's the key."
3 Don't fall victim to equipment misconceptions. Stiffer shafts and stronger lofts don't necessarily translate into more distance.
Purtzer: "My way of thinking is old school. The older you get, you want to soften up the shaft to give yourself a little more kick to get the ball to fly, to keep the ball in the air."
4 A trusty driver is a friend forever.
Purtzer: "If it works, why would you change? My driver is three generations old. There have been three upgrades since mine."
The shaft in Purtzer's driver is at least 12 years old. Moral of the story: It's hard to say goodbye to a loyal friend who has been good to you for a long time.
