Where Does It Break?
Recorded blocks with each long iron until the spread widens and the carry stops stepping evenly. That club and everything above it is the candidate zone.
What Replaces It?
A hybrid, a higher-lofted fairway wood, or a more forgiving iron. All three get tested; the first is not assumed.
Does the Ladder Still Step?
Whatever goes in has to sit at an even interval from its neighbours. A great hybrid that overlaps your five iron has not solved anything.
The finding, most sessions
The Break Is Usually Lower Than People Expect, and Sometimes Higher
The convention exists because it is roughly right for a lot of golfers, which is exactly the problem with conventions. What we find in the bay is a genuine spread of answers.
A player with moderate speed and a shallow angle of attack frequently loses the plot at the five iron rather than the four, and has been fighting a club they cannot elevate for years. A stronger player who compresses the ball well may be perfectly served by a three iron and would gain nothing from replacing it, whatever the shop wall suggests.
The tell is not the average carry. It is the spread. A long iron that still steps evenly and groups tightly is earning its slot regardless of what number is stamped on it. A long iron whose readings scatter and whose carry has collapsed toward the club below it has stopped, and no amount of loyalty changes that.
The Second Half of the Session
Once the break point is located, the replacement is chosen on its own merits rather than by category. Three candidates get tested for any given slot.
- A hybrid. Higher launch, better from poor lies, and the usual answer. Not automatically the right one.
- A higher-lofted fairway wood. Often better for a sweeper, often worse from rough, and frequently overlooked entirely.
- A more forgiving iron. Sometimes the honest answer is that the head is simply too demanding and a wider-soled iron in the same slot solves it without changing the look at address.
All three get recorded blocks. Whichever produces the even step and the tighter spread wins, and occasionally the answer surprises everyone in the room.

Why Rough Gets Tested
The whole argument for a hybrid is that it copes with lies an iron cannot. Testing one exclusively from a clean mat therefore skips the reason you were considering it.
Blocks are recorded from a clean lie, from a simulated thicker lie, and from a tight or bare one. A head that shines on all three is unusual and worth knowing about; a head that only works from perfect turf is worth knowing about too.
The Shaft Mistake
Hybrids are frequently sold with shafts far lighter than the irons they are replacing, which is why so many players hook them.
If your hybrid goes left and your irons do not, the shaft is the first place to look and the change is bench work rather than a purchase.

What the Break Looks Like in Figures
A session from last November. Note that the carry figures look almost reasonable all the way down; it is the spread column that identifies where the set stops working.
| Club | Carry centre | Step | Spread | Shots kept |
|---|---|---|---|---|
| 8 iron | 146 yd | — | 12 yd | 10 of 10 |
| 7 iron | 158 yd | 12 | 13 yd | 10 of 10 |
| 6 iron | 169 yd | 11 | 16 yd | 9 of 10 |
| 5 iron | 177 yd | 8 | 29 yd | 7 of 10 |
| 4 iron | 181 yd | 4 | 38 yd | 6 of 10 |
| 22 deg hybrid, tested | 188 yd | — | 17 yd | 10 of 10 |
| 25 deg hybrid, tested | 179 yd | — | 15 yd | 10 of 10 |
The break is at the five iron, not the four. Both the five and the four were producing carries that looked broadly plausible on their own, which is how they had survived in the bag. Put the spread column beside them and the picture changes completely: by the five iron the scatter has doubled and three shots in ten fall outside his own strike pattern.
The recommendation was two hybrids replacing the four and five, at twenty-two and twenty-five degrees, which restored an even ladder of nine to eleven yards from the eight iron all the way up. He kept the six.
One caution
Hybrids Are Not Automatically an Improvement
They launch higher and they are kinder from a poor lie. They also fly further than the iron they replace, which sounds like a benefit and is frequently a spacing problem: drop a hybrid into a four iron slot without measuring and you may open a hole below it while closing one above.
They are also harder to work and harder to hit low, which matters more than people expect on a windy afternoon in this valley.
None of that argues against them. It argues for measuring the whole ladder rather than one slot, which is why we ask you to bring every long iron you own.
