To improve your score, you do not necessarily need the most expensive set of clubs, but you do need the proper set. Unless you stand over 6 feet or under 5 feet, standard-size clubs should be correct for most men and women. Men's clubs are generally 1 inch taller per club.
The shaft is an essential consideration and, today, are usually composed of steel or graphite. While steel shafts are more durable, generally less expensive, and offer more control, they require a faster swing to generate longer distances.
Driver designs have recently reached the USGA limits for size and length. A bigger club head generates more speed through the swing, offers a larger "sweet" spot and more forgiveness.
Irons also offer a variety of styles and options, divided into two broad categories: cast irons or forged irons. Cast iron heads are recommended for beginners since they provide a large sweet spot and are more forgiving on accuracy. Forged iron heads feature a flat, weighted back which provides a higher center of gravity and results in a more concentrated sweet spot and more control for experienced players.
As with most forms of human endeavor, in golf there is not a "one-size-fits-all" solution. What's right for your partner may not be right for you. Club fitting with the help of club professional is a good place to start.
