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.
Read your session
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.
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 →
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 →
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 →
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 →
Understand ball flight
Smash factor: the contact-quality number
Ball speed divided by club speed: how much of your swing actually reaches the ball.
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 →
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 →
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 →
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 →
Choose and adjust equipment
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 →
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 a forgiving head actually buys
Forgiving 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 →
Ball fitting myths: compression charts and other folklore
Fitting a ball by swing speed is the most persistent myth in golf equipment.
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 →
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.
Read →
Build the rest of the bag
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 →
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 →
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 →
Why your fairway wood is two different clubs: the tee and the deck
The same head, same swing, and same golfer launch very differently off grass than off a peg.
Read →
The 3-wood question: who should actually carry one
The most-bought fairway wood is the one fewest golfers can use, and the data says so plainly.
Read →
Driving irons: who they actually fit, and who just wants one
A great club for a small group of golfers, and an honest engine has to know which group you are in.
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.
