Sessions — Fitting by Club

Six sessions, one document

We used to run these as six separate pages. Jump to the club you need, or read straight through — the turf board comes out earlier than you'd expect on most of them.

Sessions — Driver

Loft and Launch Are One Dial, Not Two

Golfers talk about loft as a separate setting from launch angle, but the two are welded together by angle of attack. We measure attack angle early and treat static loft as one input to a launch window, then set head mass properties before touching a shaft — a shaft can only modify what the head is already doing. Length usually comes down half an inch to a full inch from the rack, trading a mile an hour of theoretical speed for centre strikes worth several times that.

Sessions — Fairway Wood

Should You Be Carrying a 3-Wood at All?

We ask this early because for a meaningful share of golfers the answer is no. A 5-wood or 7-wood with more loft and a deeper centre of gravity converts a mis-timed swing into a shot that actually gets airborne, and the board comes out before the radar because if the sole fights the turf, nothing on the shaft rack rescues the club. Knoxville fairways go firm and thin from late July onward, which makes sole camber a real, not cosmetic, decision.

Sessions — Hybrid

Where Is Your Crossover Point?

Every golfer has a loft above which a hybrid outperforms the equivalent iron, and below which the iron still wins — finding that personal threshold is the whole session. We test the iron you own against hybrid candidates at matching lofts and compare launch, descent angle, dispersion and turf-board ground contact, with distance deliberately last on the list. Sole width is not cosmetic either: wide, cambered soles resist digging for steep deliveries, narrow ones cut cleaner through rough.

Sessions — Irons

A Set Is a System, Not Eight Copies of One Club

An iron delivered two degrees upright pulls the ball left, and two degrees flat pushes it right — entirely invisible to the golfer standing over the ball. We check lie on impact tape and a lie board before any head candidate leaves the rack. Blended sets are normal here: a forgiving long iron transitioning into a more compact short iron is common, and we specify the blend point at no extra charge because it's simply what the measurements said.

  • Lie board and impact tape first
Sessions — Wedges

Which Two Courses Do You Play Most?

Every wedge session opens with that question, because bounce is a relationship between the sole, how you deliver it, and the specific ground you stand on — not an abstract property. Around Knoxville that picture varies: some courses run coarse, firm river sand, others a softer product, and fairway turf goes from lush in May to thin and firm by September. We put candidates on the turf board and in a sand tray and watch what actually happens rather than reading the stamped letter code.

Sessions — Putter

Where Your Eyes Sit Decides Where You Aim

Eyes inside the ball line and you tend to aim right of target without ever knowing it; eyes outside and the opposite happens. We measure eye position with a mirror and a laser on the lane, and the fix is usually length — most putters we adjust come down to somewhere between thirty-two and thirty-three and a half inches. Head balance gets matched to your measured stroke arc, not a description of it, since the two disagree more often than not.
