Most golfers pick a ball by habit or by price. In under a minute, the fitting engine built from 50 years of professional clubfitting scores 70 ball models against your swing — and hands you the one that fits.
The same scoring engine that powers the AI Golf Club Builder — compression matched to your swing speed, flight window, greenside spin, feel and cover — applied to every ball in the catalog. No email address. No credit card. Just the answer.

How It Works
The same discipline as a studio fitting.
This isn't a quiz that guesses. It's a scoring engine built from decades of TrackMan sessions, thousands of fittings, and an engineer's insistence on measurable answers.
01
You describe your swing
Swing speed sets your compression window — the single most important match in ball fitting. Attack angle, flight window, spin and feel refine it.
02
The engine scores every ball
All 70 models from 22 manufacturers are scored server-side against your profile — compression, flight, greenside spin, feel, category and cover, each weighted the way a master fitter weights them.
03
You get a ranked answer
One best-fit ball with the reasons why, plus the ranked alternatives — including a printable fitting report to take to the shop or the first tee.
The Physics
Spin is a three-axis problem.
"Foundational for launching missiles and golf balls alike." A golf ball rotates around three axes at once — and every ball in the catalog behaves differently on each of them. That's what the fitting engine analyzes.
Off the driver, back spin (rotation about the X axis) is what keeps the ball in the air — too much and it balloons, too little and it falls out of the sky. Side spin (rotation about the Z axis) is your hook and your slice. And how much of each a ball produces depends on its compression, its cover, and how your swing delivers the club.
That's why the fitting asks about swing speed, strike quality, tee height and attack angle: together they define the spin picture your swing creates — and the engine finds the ball whose construction complements it.
X Axis · Back SpinLift, carry and stopping power — driven by compression and cover
Z Axis · Side SpinCurvature — a lower-spin ball straightens the miss
Y Axis · Roll AxisThe line of flight the other two axes tilt around
The Catalog
Is your ball in here? It's been analyzed.
Every one of these 70 models across 22 manufacturers — from six countries has been profiled for compression, spin, flight, feel and cover — and every fitting scores all of them. Search for the ball you play today, then run the fitting and see where it ranks against your swing. Updated for the 2026 releases — including the new TaylorMade TP5 generation, Callaway Chrome Tour line, Bridgestone Tour B VeloSurge family, and the all-new XXIO Hyper RD — plus Kirkland Signature, Precept, Saintnine (Korea), Kasco (Japan) and Inesis (France).

Miura Golf · Featured Dealer
Miura's first Featured Dealer in the United States
Japanese forged-iron maker Miura Golf named California Master Clubfitter David Butler its first Featured Dealer — honoring fittings that ran two to five hours, built on TrackMan data, computerized shaft analysis, and tolerances measured like engineering, because they were.
ABC News · Wayne Freedman
The science and patience of true custom fitting
ABC News reported on a fitting process centered on launch-monitor analysis and patient observation of real ball flight — hours, not minutes — producing straighter shots, better smash factor, and more distance than off-the-rack sets.
Jay Stuller · Feature Profile
"Making error-free arrows"
Writer Jay Stuller profiled the Doctor Grip fitting — one that begins over breakfast, reading the golfer before a club is swung, then applies a former Chrysler chief engineer's precision to every shaft, loft and lie.
The Fitter
From gripping clubs to fitting the ball itself.
"With a degree in Mechanical Engineering and over 50 years of experience in golf club design, manufacturing, building and fitting — using TrackMan, physics, aerodynamics and mathematics in my unique fitting process — I built a worldwide fitting business as customers came to me from all over the world. Using AI, I now have the means to implement my technology into worldwide products, and to provide you with the finest fitting processes available for building your set of golf clubs. This is leading-edge technology — the first of its kind."
David Butler"Doctor Grip" · BSME · MBA · Professional Master Clubfitter
David Butler — "Doctor Grip" — is a Professional Master Clubfitter with roughly 50 years in club repair, design, building and fitting. He met Jack Nicklaus at Ohio State in the 1950s, spent 15 years as a Chief Engineer at Chrysler, contributed to NASA's Magellan Venus mission, and consulted in Silicon Valley for a quarter century. He is also a national champion in NHRA fuel dragster racing. Precision is not a marketing word to him. It's a habit.
One question followed him through thousands of club fittings: fitting the clubs is great — but which ball? The industry's answer was trial and error. His answer was an optimizer, first proven in Excel against published tour launch data, then rebuilt with AI into the engine behind this site — predicting the optimal ball from launch speed, launch angle, temperature and altitude.
That's how he went from gripping clubs, to designing them, to building them, to fitting them — to fitting the ball itself. This site gives that answer away, free, to any golfer who wants it.
