Fitted On Four Lies, Because Only One Of Yours Is Clean
Most fitting sessions in this valley happen on a flat rubber mat with a
perfect tee-height ball and a fan pointed at your back. That is a fine place to start and a poor
place to stop. Rough Fit Lab keeps a strip of real turf behind the bay, and no specification gets
written until it has survived four surfaces: mown grass, bare summer ground, a kikuyu collar, and
rough that has settled the ball down into it.
Four numbers, one club. The build we ship is the one whose fourth number
stays honest — not the one that wins the first.
The premise
A Mat Hides The Only Variable You Cannot Control
Turf is the one thing in a golf swing that changes every single shot and answers
to nobody. You can standardise the ball, the shaft, the loft, the grip and the hour of day. You
cannot standardise what is under the ball on the twelfth hole in August.
When a club is chosen on a mat, the mat quietly does part of the work. It gives the sole a hard,
flat, frictionless surface to skid on, so a wide sole and a narrow sole look nearly the same. It
keeps grass out of the impact, so a head that traps a blade of rye behaves exactly like a head that
slices through it. It sets the ball on a surface with no give, so a leading edge that would dig on a
real lie never gets the chance to prove it. None of that is dishonesty on the mat's part. It is
simply a surface with one behaviour, asked to represent a game played on many.
What we do instead is boring and repeatable. Behind the bay there is a fenced strip roughly
eighteen paces long, kept in four distinct states through the year. Every candidate club gets a
block of swings on each state, in the same order, with the same ball, inside the same hour. The
launch monitor sits outdoors for that portion of the session. The numbers that come back are not
prettier than indoor numbers — they are usually worse — but they are the numbers that
describe the club you are actually going to carry.
What this is not
This is not a lesson, and it is not a swing clinic. We do not rebuild your action, we do not
sell a coaching package, and we will not spend your bay time telling you to shallow the club. We
measure what your swing does today and match hardware to it. If your motion changes materially
later, come back and we will re-run the ladder against the new version of you.
The method
Four Rungs, Same Order, Every Session
We call it the lie ladder. Nothing clever about
the name — it is a list you climb, and a club is allowed to fall off it.
Mown fairway turf
Cut to about half an inch, watered on the normal cycle. This is the
control rung and it is the only one where a club is expected to look good. If a head cannot
post a clean number here, it never reaches rung two.
Bare valley ground
A worn patch kept deliberately thin and unwatered from June onward,
which is what a Central Valley fairway becomes by the middle of a dry summer. Sole width,
leading edge height and effective bounce all show their real character here.
Kikuyu collar
Thick, wiry, grabby, and everywhere in this part of California. The
ball sits up but the grass fights the hosel. This rung sorts out which heads twist on contact
and which ones hold their face angle through the strike.
Settled rough
Grown out and pressed down so the ball nests rather than perches.
This is where face progression stops being a matter of taste and starts being a matter of
whether the leading edge can get underneath at all.
Head shape, shaft profile and length settled against a measured strike pattern rather than a
stock chart. Two rungs only, since nobody plays a driver out of settled rough on purpose.
A ladder card is not a wall of data. It is three columns that mean something,
repeated across the four surfaces, so you can see where a club gives up.

Reading
What it answers
Why it moves
Speed held
How much of your rung-one ball speed survives on the harder surfaces.
Grass between face and ball, and off-centre contact caused by the lie.
Entry
Where the sole first touches down and how far it travels before it exits.
Sole width, camber, effective bounce and how firm the ground is that week.
Presentation
Whether the leading edge can still get under a ball that has settled.
Face progression, offset, hosel setback and the height of the leading edge at address.
You leave with that card printed on card stock, one page per club family, with the raw block
averages on the reverse. It is deliberately not emailed as a spreadsheet. A printed sheet gets kept
in a bag pocket and pulled out two seasons later when something feels off; a spreadsheet gets lost
in a mail thread within a week.
In their words
Two Notes From The Book
I came in convinced I needed a stiffer shaft. What actually showed up
was that my four and five iron were losing about a tenth of their speed the moment the ball sat
down at all. Arman put a wider sole under the two of them and left the shafts alone. Cheapest
fix I have ever been talked into.
Devin Sarabia · Clovis · 9 handicap
The turf plot sold me. I have been fitted three times before and every
one of them was indoors on a mat. Watching the same club hit four different ways in twenty
minutes made the whole thing obvious in a way a spreadsheet never did.
Fitting in Fresno is not the same job as fitting in Portland or Charlotte. The
ground here changes character twice a year, hard, and a club that suits one half of the calendar can
be a liability in the other.
Roughly May to October
Hard, thin, unforgiving
Fairways firm up, lies go bare in the traffic areas, and anything with a broad flat sole
starts bouncing into the equator of the ball. This is the half of the year where narrow soles,
modest bounce and a leading edge that sits low earn their keep. It is also the half where a
session at seven in the morning is the only comfortable option.
Roughly November to March
Soft, overseeded, grabby
Winter rain and overseeded rye leave the ground receptive and the collars thick. Now the
wider soles and higher effective bounce that were a problem in August are quietly saving you two
shots a round. We keep both sets of readings on your card so a seasonal swap is a five minute
decision instead of a guess.
Next step
The Bay Holds One Player At A Time
There is a single fitting bay and a single turf plot, so the calendar is genuinely finite. Most
weeks we take eleven or twelve sessions. Tuesday and Wednesday close at three, Thursday and Friday
run to six, and Saturday mornings start at half past six because by ten in July the plot is
unusable.
Tell us what is in the bag, what is annoying you about it, and roughly when you can get here. We
will reply with two or three slots and an honest note about whether the thing you are worried about
is worth a full ladder or a twenty minute look on the bench.
