Six Blocks, One Protocol

Launch and Spin Are a Pair, Never a Target

There is a persistent idea that a driver fitting is a search for a published launch and spin combination. It is a tidy story and it falls apart the moment you notice that the published numbers were derived for a clubhead speed, an angle of attack and a ball that may have nothing to do with yours.

What actually matters is the relationship between the two on your delivery. A golfer swinging down on the ball needs loft from somewhere, and taking spin out of that flight without adding launch produces a ball that falls out of the sky early. A golfer swinging up has the opposite problem and the opposite solution. Chasing a spin figure in isolation is how people end up with drivers that measure beautifully in a room and lose thirty yards into a breeze.

So the card reports launch and spin together, with descent angle beside them, and marks all three as modelled where they are modelled. If the winning configuration gets there with more spin than the internet would recommend, and the dispersion and the descent angle are both better, that is the configuration we recommend and the card explains why.

A driver that is nine yards shorter and stays in play twice as often is not a compromise. It is the correct club, and the carry column will argue with you about it.

Roughly one driver block in five ends with us recommending nothing beyond a length change and a grip. That is a completed block, the paperwork is identical, and the fee is the same.

The Shortest Change With the Largest Effect

Stock three woods run around forty-three inches. That length exists to protect a tee-shot carry number in a catalogue comparison, and it makes the club measurably harder to control from the ground. Taking half an inch out costs a yard or two of theoretical distance and typically tightens the strike pattern by several millimetres, which is worth considerably more than the yard.

Shaft weight tends to move upward too. A lighter shaft in a long club encourages the hands to throw the head at the ball early, which is exactly the delivery that produces the fat-then-thin alternation people complain about. Adding fifteen or twenty grams often steadies the low point without the golfer being able to say why.

Both changes get tested against your own club rather than assumed, and both go on the card with the before and after figures. If the shorter, heavier build does not beat what you brought, the card says so and you keep what you have.

The measurement that predicts fairway wood happiness best is not carry. It is the percentage of shots that came off the middle of the sole.

When weather closes the lane, the indoor half runs normally and the card is marked provisional. We will not sign off a fairway wood build on mat data alone, because the mat is the one surface that hides the fault we are trying to fix.

Length and Lie Get Set From the Iron, Not the Wood

A hybrid replacing a four iron should be set up like a club you can hit from the ground, which means it usually wants to be shorter than the length it ships at. Stock hybrid lengths are built around a tee-shot use case and around the same catalogue distance pressure that inflates fairway wood lengths.

Lie angle matters here more than most people expect. A hybrid soled with a lie that suits a fairway wood arrives with the toe up for a golfer who stands to it like an iron, and the ball starts left of where it was aimed. We check dynamic lie on the sole board exactly the way we do for irons, and we bend hybrids that can be bent.

Shaft choice tends to follow the iron set rather than the wood set. Matching the hybrid shaft to the iron shaft weight, rather than to the driver, keeps the transition through the top of the bag from feeling like a different sport. Where a golfer's irons are graphite this is straightforward; where they are steel, we usually land on a heavier hybrid shaft than the stock option.

The finished spec is written to sit inside the ladder you already have. If it carries 197 and your five iron carries 183, the gap below it is now fourteen yards and the gap above it needs checking against your fairway wood. That whole ladder goes on the card.

Read Off the Sole, Not Off a Chart

Static lie is measured on a fixture with the club soled flat. Dynamic lie is the angle at which the sole actually meets the ground during your swing, and it is the only version that affects where the ball starts. The two can differ by several degrees, particularly for taller golfers and for anyone whose hands are noticeably low or high at impact.

We read it from a sole and face board: a strip of impact material on the sole, a marked board under the ball, and a look at where the mark sits after the strike. Toe-first contact means the lie is too flat for you and the face is pointing right at separation. Heel-first means the reverse. The correction is a bend, it takes minutes, and it is measured before and after with both figures on the ticket.

Length interacts with all of it. Lengthening a club flattens the effective lie and moves strike toward the heel; shortening does the opposite. So we settle length first, then read dynamic lie against the length we are going to build, rather than fitting lie to the club you walked in with and then changing the club.

The whole set gets checked, not just the seven iron. Lie requirements drift through a set because the clubs are different lengths and you stand at a different distance to each one, which is precisely why manufacturers build a progression in and precisely why that progression may not be yours.

Grooves Do Less Than the Advertising Suggests

Fresh grooves matter most on the shots where something sits between the face and the ball: wet grass, a flyer lie, a ball with a scuff on it. From a clean, dry, tight lie the face texture and the loft are doing most of the work, and a two-season-old wedge in reasonable condition is not the reason a pitch ran through the green.

What we can measure is the decline. A wedge face gets photographed and the groove edge radius recorded at the fitting, which gives a reference point for later. When somebody comes back eighteen months on convinced the wedge has gone flat, we can compare rather than guess, and about half the time the wedge is fine and the ball model changed.

Ball choice moves wedge spin more than most component changes do. A firm distance ball and a soft urethane ball can differ by well over a thousand revolutions on a partial wedge shot, which is a bigger effect than any grind on this page. Bring a sleeve of what you play and we will measure both.

Nearly every golfer who tells us their wedges have stopped spinning has changed something other than the wedges.

What a Putter Block Can and Cannot Do

It can fix aim. Aim error is measurable, it is largely a function of head design and eye position, and correcting it is the single most reliable improvement available in this block. Golfers who aim two degrees right and compensate with a pull are extremely common and the compensation is never perfectly consistent.

It can improve start line by matching hang to arc, and it can improve distance control by matching head weight to the speeds you actually putt on. Both of those show up in the four-round follow-up more often than not.

It cannot fix green reading, and it cannot fix a stroke that changes shape under pressure. If the camera shows a stroke with no repeatable pattern at all, we will say so and suggest the money is better spent elsewhere. That happens perhaps one block in ten, and we would rather say it than sell a putter into it.

Most golfers do not need a different putter. They need the one they have to be an inch shorter, two degrees flatter, and aimed where they think it is aimed.

Length, lie and loft corrections on your existing putter are bench work and can usually be done the same afternoon. Roughly four putter blocks in ten end that way.
