Mapping Ball Speed Retention Across the Driver Face
A face that gives back 94 percent of centre-strike ball speed half an inch toward the toe is worth more to most players than one that peaks two miles per hour higher in the middle.
Open note →Notes Written Between Builds
Six entries so far, grouped around the three things this shop measures that most fittings skip. They are written for golfers who want to understand the reasoning rather than be handed a conclusion.
Humidity, Cold Fronts, and the Ball Speed You Actually Keep
Numbers recorded in August on the Gulf Coast do not transfer cleanly to a 51-degree January morning. Here is how much moves, and which part of it belongs to the club.
Open note →Face Progression, Offset, and What Your Eye Sees at Address
Two irons can share a loft, a lie and a length and still look nothing alike over the ball. The difference usually sits in how far the leading edge stands ahead of the hosel.
Open note →Reading Face Progression Through a Blended Iron Set
Mixing a cavity long iron into a muscleback scoring set is normal now. What is not normal is the step in progression that happens at the seam if nobody measures it.
Open note →Turf Interaction: Bounce, Sole Width, and the Ground Under You
The sole is the only part of an iron that touches the course. We measure how it enters, how it exits, and how much speed the ground takes back from you.
Open note →Wedge Fitting for Bermuda Grown Over a Sand Base
Most wedge grinds are designed around cool-season turf on a clay profile. Southwest Florida is neither, and the fitting answer changes because of it.
Open note →The Three Threads
Ball speed retention is about what the face gives back when you do not catch it perfectly, which is most of the time. It is the single most useful thing a launch monitor can tell you and the one most fittings never look at.
Face progression is about geometry you can see at address and cannot easily describe. It changes where your hands want to be, which changes delivered loft, which changes everything downstream.
Turf interaction is about the only part of the club that touches the golf course. On Bermuda grown over sand it behaves differently enough that borrowing conclusions from elsewhere will lead you wrong.
Read It, Then Come and Measure It
None of this is worth much in the abstract. It is worth a great deal with your own numbers next to it.
