Golf Equipment for Amateurs: Choosing Clubs

Equipment decisions are easier once you separate the three questions that get mixed together: what the Rules allow, what a fitting can measure, and what is simply preference. This article takes them in that order.

What the Rules allow

Club length. A club other than a putter must be at least 18 inches and no more than 48 inches. Since 1 January 2022 a committee running a professional or elite amateur event may adopt Model Local Rule G-10, which caps clubs other than putters at 46 inches with a 0.20-inch measurement tolerance; making a stroke with a longer club then means disqualification, while carrying it without playing it carries no penalty. The governing bodies state that G-10 is not a Rule of Golf and is not aimed at recreational play.
Fourteen clubs. The limit on clubs carried is a Rule of Golf, not a local option, and it applies from the first stroke of the round.
Conforming equipment. Clubheads, shafts, grips and balls must conform to the equipment rules; the USGA publishes conforming lists and an equipment FAQ for exactly this question. Check a second-hand driver against the list before a championship, not after.

What a fitting can measure

A fitting session is a measurement exercise. What comes out of it that you can act on:

Carry distances per club, measured on one machine in one session, which is the only way to find gaps and overlaps in a set.
Dispersion, the left-right spread, which matters more than the longest shot of the session.
Launch and spin, which decide whether your driver is losing distance to a flight that climbs and stalls.
Lie angle on irons, which can be demonstrated with tape and a board rather than argued about.
Grip size, the cheapest change with a noticeable effect.

What a fitting cannot honestly promise is a number of strokes. Published comparisons between fitted and unfitted sets are overwhelmingly produced by the companies that sell fitting, and we found no independent peer-reviewed study quantifying the scoring benefit for mid-handicap amateurs. Treat a promised handicap drop as a sales claim and the measurements as the real product.

Where preference legitimately rules

Blades against cavity backs at a given handicap: forgiveness is real, but so is confidence in a shape you like looking at.
Shaft feel. Flex designations are not standardised between manufacturers, so a "stiff" from one brand can match a "regular" from another. Weight is the more comparable number.
Ball choice. Within a category the differences are small compared with the difference between a premium ball and a distance ball around the green.
Putter style. Fitting can set length and lie; alignment preference is yours.

A sensible buying order for an amateur

Get the wedges and putter sorted first. They are used on the majority of scoring shots.
Then irons, fitted for lie and length rather than bought by brand.
Then the driver, which is the club most sensitive to shaft weight and launch conditions.
Balls last and in bulk. Pick one model and stay with it so that your distance control means something.

Travelling with clubs to a championship

Check lie angles and grips after a flight; bags are not handled gently.
Carry a spare glove and spikes rather than a spare driver.
If the event has published a local rules sheet with G-10 in force, measure your driver before you travel.
Keep the receipt or conformity details for any club bought second-hand.
