Golfers will spend an hour debating driver heads and thirty seconds on the shaft attached to it. That's backwards. The shaft is what delivers the head to the ball, and changing it changes more than changing the head.
Flex isn't a standard
Start here, because it undoes a lot of received wisdom. There is no industry standard for shaft flex. One manufacturer's Stiff can be softer than another's Regular. The letters — L, A, R, S, X — are marketing labels, not measurements.
What is measurable is frequency (how fast the shaft oscillates) and torque (how much it twists). Fitters use those. The letter on the shaft tells you very little on its own.
Which means "I play stiff" is not actually information, and buying by letter across brands is guesswork.
Weight matters more than flex
The most under-appreciated fact in club fitting. Shaft weight affects your tempo, your sequencing and your strike quality more than flex does.
Too heavy and you'll struggle to get the club moving, lose speed, and often get stuck behind you. Too light and you'll lose the sense of where the head is, and your strike goes.
Rough guides, and these vary widely by player:
| Club | Typical range | Notes |
|---|---|---|
| Driver | 45–75g | Lighter for slower swings; heavier if you're quick and get loose |
| Irons (steel) | 95–130g | Standard steel is around 115–120g |
| Irons (graphite) | 55–100g | No longer just for slow swingers |
Graphite iron shafts have shed their reputation and are worth serious consideration for anyone with a sore back, sore elbows, or a slower swing. The performance gap against steel largely closed some years ago.
Kick point, in plain terms
Kick point — or bend profile — is roughly where the shaft flexes most.
- Low kick point — bends nearer the head. Higher launch, higher spin. Helps get the ball up.
- Mid kick point — the middle ground, and where most players belong.
- High kick point — bends nearer the grip. Lower launch, lower spin. For players who already launch it high.
It's a smaller effect than weight or flex, and a much smaller effect than the marketing implies. Get weight right first.
Grip size, while we're here
The other five-minute fix nobody makes. A grip that's too small encourages excessive hand action; too large restricts it. If you fight a hook, going slightly larger can genuinely help. If you can't release the club, you may be gripping something too thick.
Grips also wear out far faster than people replace them. A set played weekly wants replacing roughly annually — and worn, shiny grips make you hold on tighter, which wrecks everything downstream.
Priority order
- 1. Weight
- Biggest effect on tempo and strike
- 2. Flex
- Matters, but ignore the letter — compare on feel and ball flight
- 3. Lie angle
- Cheap, quick, and commonly wrong
- 4. Grip size
- Cheap, quick, affects release
- 5. Kick point
- Real but minor. Last thing to worry about
- Replace grips
- Roughly annually if you play weekly
What this means practically
If you're spending money on equipment this year and you have to choose, a proper fitting on the clubs you already own will usually beat a new club bought off the rack. New shafts in your current irons, correct lie angles and fresh grips will cost a fraction of a new set and change more than the new set would.
That's an unglamorous recommendation and it's the right one for most golfers.
