There are two reasons golfers who hit the ball on the upswing achieve the optimum combination of launch and spin. First, the ball is being launched higher on the upswing. In most cases this is the preferred condition because the majority of us launch the ball at too low of an angle. Second, because of the upward path of the driver, the ball will be exposed to less of an oblique face angle (see below). This means less spin will be imparted on the ball at impact. This is also a preferred condition because most of us spin the ball too much to achieve maximum distance with the driver. A downward attack angle of the clubhead, as opposed to a horizontal path, will present a more oblique face angle to the ball (like an iron) and in most cases create more spin. At the same time, the downward motion produces a lower launch angle. Combined with the high spin this produces less than ideal launch conditions. Therefore, assuming club properties remain the same in all cases, launching the ball at a higher angle is the primary cause for longer drives of those who hit it on the upswing.

I use clubs with a D-1 swingweight, but I like the feel of D-3 better. How do I increase the swingweight without having to buy new clubs?
Adam Slansky, New York

Adding weight by placing lead tape on the back of an iron clubhead is the only appropriate way to change swingweight. A change in swingweight of three points or less is rarely detectable by most swingweight-sensitive golfers. If you can feel this change and the adjustment has made a difference to your game, then go for it.

Is it important to have the same swingweight in your iron set and woods?
William W.S. Lei, Australia

In recent times, golfers have been asking for slightly lighter clubs, but the swingweights are generally the same for woods and irons. Start your search with the same swingweights, and change only if you have a problem. The standard swingweight is D-2, but it’s important to feel comfortable.

Shouldn’t most amateurs choose a club with forgiveness rather than workability?
Scott Young, Atlanta

Some of the best players in the world choose to use blades, but you first need to be able to hit the sweet spot on a regular basis. It’s the difference between being an artist and an amateur; Picasso needed to manipulate a fine brush easily to exhibit his skills, but you should choose the big brush.

Do certain clubs offer a higher grade of titanium than others, resulting in hotter faces?
Nick Iordanis, Toronto

Yes, but although materials and construction of clubheads vary, a driver’s maximum “hotness” is limited by the rules. Some titanium alloys (SP700, for instance) offer certain design freedoms, but don’t think materials will change your performance as much as increasing your swing speed and producing more consistent contact with the sweet spot.
