How do I choose a golf driver?
For example, if you hit the golf ball low off the tee, you should find a driver that has a high trajectory rating. Don't think that trajectory rating is the same as loft. For instance, a driver may have a 10-degree loft, but if its center of gravity is toward the front, it will react more like a driver with an 8-degree loft.
What should seniors golfers consider when buying a driver?

What loft should your driver be?
The ideal driver loft depends on your swing speed and the attack angle. Average players that swing the club less than 95 MPH will likely find that a 10.5-degree driver performs the best. Better players who can control their drives and want the most distance will lean more towards a 9-degree driver.
Should I change the loft on my driver?
Lower lofts can provide more energy transfer at impact because there's less of an oblique angle. It's why your 7-iron flies farther than your 8-iron. In our test, drivers with less loft consistently produced more ball speed, even for low swing-speed golfers (3.2 mph more compared to the 10.5 and 12-degree drivers).
Does adding loft to a driver open the face?
When you lower the loft of a golf club, you are also going to close the angle of the clubface. If you increase the loft on a club, you will open the face angle on the club. This applies when you are adjusting loft on the driver as well as irons or hybrids.

How much loft do you need for a golf driver?
If your swing speed is over 100 mph and you hit the golf ball a long way, you should have a driver with a loft of about 12 degrees, or less , and that will produce less backspin. But if you are like most golfers with swing speeds that are below 90 mph, you will need a more lofted driver that increases that backspin to keep the ball aloft.

Why do higher COR clubs not work?
Higher COR clubfaces do not work in the manner of a spring. In the collision between the clubface and the ball, there is always some energy lost. This is because of several reasons but mainly due to the face flexing inward while the ball is compressed against the face. Both actions result in a loss of energy.
What does a high COR mean?
Hence a high COR means more distance regardless of your clubhead speed. If you like math and you’re interested to know more about the relationship of the factors that control ball speed as a result of impact or how much more distance you can get with a higher COR clubhead, here is the tried and true mathematical relationship between all ...
What does a COR of 0 mean?
Thus a collision which yields a COR of 0 means no energy is transferred between the two objects while a COR of 1 indicates a perfectly elastic collision in which all energy is transferred from one object to the other. The COR rule also became known as the “spring face rule.”.
Is a higher COR clubface a spring?
This term is misleading because in fact, a higher COR clubface does not really act like a spring. When you think of a spring face, it is logical to think the ball causes the clubface to flex inward, and upon flexing back out the ball is propelled as in the manner of a trampoline sling-shotting a gymnast upward.

Why do golf clubs swing sideways?
Many golfers think they’re not good enough to get custom-fit clubs, that the flaws in their swing will override any potential benefits of clubs built just for them, but fitters say the reason many players hit it sideways is because they haven’t been custom-fit. Trying to swing golf clubs whose length, weight, lie angle, shaft flex or grip size don’t match the body encourages players to make unnatural compensations that prevent them from developing proper mechanics. Choosing this type of driver will cost you a little more time and money, but it ensures you’ll get a perfectly-fit driver.
What is driver loft?
LOFT. Loft is the amount that the face of the club slopes back. Driver loft, which typically ranges from 8.5° to 15°, should match your swing speed. The slower your swing speed the more loft you should have.
How long is a standard driver?
No standard length exists for a driver. Every manufacturer offers different models with varying lengths (usually 43.5” to 47”) but drivers continue to get progressively longer, with some even reaching 48” (the maximum allowable). That’s because in most cases, the longer the shaft the faster the head will travel.
Can you adjust the face angle of a golf club?
Using only a wrench, golfers are now able to adjust the face angle, loft and lie angle without the help of their local club fitter—or having to buy a new club altogether. Golfers can alter the club dynamics to suit their desired ball flight or pick up a few additional yards of carry. Many manufacturers insist an adjustable driver gives you every advantage. However, others disagree, citing a more expensive price tag, additional weighting in less than ideal locations, and confusion about all the different setting combinations as reasons to play a traditional, non-adjustable driver.
Can you custom order a driver?
Many drivers can also be custom ordered. Customers can select a custom shaft and grip, as well as length fit to them. All custom orders are placed directly with the manufacturer and assembled by the experts that make the clubs. This is a great option if you have been custom fit for a driver.
Does the CT test always mimic the response of a golf ball?
Olsavsky’s gripe is that the CT test doesn’t always accurately mimic the response of a golf ball. “When you’re pinging [the steel ball in the CT test] a half-inch or more off-center, you get a higher response,” Olsavsky says.
Is it illegal to use a CT test on a golf club?
Therefore, any golf club that measures higher than 257 milliseconds on the CT test is deemed illegal. The CT test, being that it’s just a small pendulum device, is “really easy to use,” according to Olsavsky. Actually, some OEM Tour Trucks that travel to PGA Tour events each week have a CT testing setup right in their truck.
