I love this test.

Go to the driving range. Set aside 20 balls. Take the first 10, and make three-quarter swings. Note how far the balls go (both left-right and how far away from you.)

Now take the next 10, and try to launch them as far as you can. Note how far the balls go (both left-right and how far away from you.)

For most golfers, the balls you 'crushed' will be farther than your 3/4 swings, but probably not by much. And I'm willing to bet your dispersion (balls left-right) will be much worse with the 'crushed' balls.

I say this everytime someone wants to be longer. More important than getting longer is knowing how far each club carries right now. Length is not equal to lower scores. If you can find a way to get longer (and keep the ball in the short grass at the same time) then by all means, get longer. But sacrificing accuracy for length is a fools errand.

A new highlight: Golfing the home course on Christmas Day.

I say it too often: If it's golf club shaped, you can play with it.

For the record, I'm a club doctor, not a swing doctor.
