Mapping Speed Loss Zone by Zone Across a Driver Face
We taped forty drivers and logged what each miss actually cost in ball speed. The penalty is not symmetrical, and the cheapest miss is not where most players assume.

Notes From the Bench, Not From a Catalogue
Everything below started as a note on a build record. When the same observation turns up often enough across enough players, we write it out properly and put it here. There are no product launches on this page and nothing on it is sponsored.
What a Forty-Degree Morning Takes Off Your Tee Shot
Houston gets maybe fifteen genuinely cold mornings a year, and every one of them costs distance. Here is where the yardage goes and which part of it you can build back.
Read the note →Face Progression: The Iron Spec Nobody Reads Off the Box
How far the leading edge sits ahead of the hosel changes your start line, your dynamic loft and how the club looks at address. It is rarely published and never matched.
Read the note →Why a Heel Strike Curves Back and a Thin One Does Not
Gear effect is the reason a driver forgives a heel miss and a three iron punishes it. Bulge, roll and centre of gravity depth, explained from strike tape rather than theory.
Read the note →Leading Edge Height and Why September Turf Punishes It
The same wedge that works in June skulls the ball across the green in September. Effective bounce, measured at your actual shaft lean, is what changed — not your swing.
Read the note →Sole Width, Camber, and the Habit of Digging
A wide sole is not automatically forgiving. Where the camber peaks and how the trailing edge is relieved decide whether a club exits the turf or buries in it.

How these get written
One Observation, Repeated Enough Times to Trust
A single session never becomes an article. Reuben keeps a running column on the side of the build sheets for anything that looked odd, and Thea does the same on the iron bench. When a pattern shows up across thirty or forty records, somebody sits down and writes it up with the numbers attached.
That is deliberately slow. It also means nothing here is a repeat of a manufacturer white paper, because manufacturers do not measure the clubs their customers already own and we do, every single session, whether or not anything gets bought that day.
If a note here contradicts what somebody told you at a retail counter, bring it in. We would rather be argued with in person than be right on a web page.
Rather Read Your Own Numbers?
Every session starts with an audit of the clubs you walked in with. That sheet is more useful than anything on this page, because it is about your bag rather than the average of forty of them.
