Launch-monitor literacy
The same knowledge base that powers the fitting engine, in readable form. Short, sourced, and honest about what the numbers can and can’t tell you.
Smash factor: the contact-quality number
Ball speed divided by club speed: how much of your swing actually reaches the ball.
Read →
Spin, spin loft, and why 'low spin' isn't always the goal
Spin holds the ball in the air, and the right amount depends on your speed.
Read →
Launch windows: why your optimal launch isn't the tour's
Optimal launch depends on your speed and your attack angle, not a universal number.
Read →
Descent angle: the green-holding number nobody checks
The descent angle that holds a green rises with your speed, from about 41° up to 46°.
Read →
Shaft flex: useful starting point, terrible gospel
There is no industry standard for flex, so bands by speed are where you start, not where you finish.
Read →
Why the ball curves (and what equipment can honestly do about it)
Curve comes from the gap between face angle and swing path at impact.
Read →
Wedge gapping: the 4–6° rule and why your PW loft decides everything
Wedge setups are built down from the pitching wedge in 4–6° steps, and most bags skip one.
Read →
Hybrids vs. long irons: the crossover is a physics question
If your longest iron can't land steep enough to hold a green, it isn't earning its bag slot.
Read →
Optimal driver numbers by swing speed (and why the charts disagree)
Your optimal launch and spin depend on your speed, and the two best-known sources don't fully agree.
Read →
What your Trackman session actually gave you (range vs. bay)
Trackman Range and a Trackman fitting bay are different instruments wearing the same logo.

How to read a fitting quote (the second-opinion checklist)
The spec sheet is the product, so here is how to pressure-test a big fitting quote before you pay it.
Read →
Ball fitting myths: compression charts and other folklore
Fitting a ball by swing speed is the most persistent myth in golf equipment.
Read →
Attack angle: the cheapest distance in golf
Hitting up on the driver is worth more carry than any purchase at the same swing speed.
Read →
How many shots make a real session?
Six-plus representative shots per club, because averages beat highlights.
Read →
Measured vs. modeled: not all launch monitor numbers are equal
Range setups estimate some numbers, and knowing which changes how much to trust them.
Read →
What each fitting change actually moves (the honest levers table)
Independent measurements of every fitting lever, and the noise floor any change must beat.
Read →
Shaft fitting from numbers: what's real, what's personal
Group tests show tiny average differences between shafts, and large unpredictable individual ones.
Read →
Forgiveness, measured: what high MOI actually buys
High-MOI heads retain 5–8% more ball speed on mishits, and add almost nothing on pure strikes.
Read →
What your adjustable hosel really changes
A loft sleeve moves loft, face angle, and lie together, and knowing the coupling is the fitting skill.
Read →
Altitude, temperature, and your real carry numbers
Thin air adds about 1.1 to 1.2% carry per 1,000 ft, and every 10°F costs the driver around 2 yards.
Read →
Bounce and grind: the wedge variables loft can't decide
Bounce is fit to how you deliver the club and what you play from: steep diggers need more, sweepers less.
Read →
The spin you lose to water and worn grooves
Wet conditions and old grooves cost more wedge spin than any equipment upgrade adds.
Read →
Swingweight and lead tape, without the folklore
Swingweight is a balance ratio, not a law of physics; useful for consistency, oversold as a fitting fix.
Read →
Lie angle: the direction adjustment hiding in your irons
Too upright starts shots toward your hook side, too flat toward your slice side, about 4 yards per degree.
Read →
Combo iron sets: forgiveness up top, feel where you score
Mixing two iron models in one bag is normal; fit the transition by loft gap, not by the number on the sole.
Read →
Buying used clubs with confidence (the checklist)
Used tour-level gear at a fraction of retail is real value, if you verify specs, check wear, and know the floor.
Read →
Fast swing, high handicap: fit the pattern, not the speed
Plenty of speed with a big miss means stability and face control are the fitting; distance is already solved.
