Tiger Woods

The PGA Tour's decision to start testing for illegal equipment is a good first step, Tiger Woods said. But he wishes more could be done. "The PGA Tour has taken a step in the right direction and I'm happy about that," Woods said after playing a pro-am at the Western Open. "It's just a matter of making sure that the game is preserved, it's policed.

"It's the greatest game in the world, and I want to see it stay that way." Tour Commissioner Tim Finchem announced that beginning in January, a portable device will be available at all tour stops so players can measure the springlike effect of their drivers, letting them know for sure if they're "hot" or not.

Thanks to technological advances, golf has seen monstrous leaps in distance in recent years. But some golfers — Woods included — are worried that technology is crossing the legal line.

The issue is a physics term called the "coefficient of restitution" (COR), which measures how quickly a golf ball springs off the face of a club at impact. When the face is ultra thin, it allows for more of a trampoline effect.
