Everything we know about playing better golf.

Swingweight is a measurement of how a golf club’s weight is distributed and how heavy the clubhead feels relative to the grip when the club is swung. It is measured on a standardized scale using a 14-inch fulcrum and expressed with letter-number values such as D2 or D4. There is no USGA or R&A swingweight limit.

Smash factor is ball speed divided by club speed, a Trackman metric that describes how efficiently club speed is converted into ball speed. A driver smash factor near 1.50 is an excellent benchmark; for example, 100 mph of club speed with a 1.50 smash factor produces about 150 mph of ball speed. The USGA and R&A regulate clubhead spring effect through equipment-conformance tests rather than by setting a smash-factor limit.

Dispersion is the pattern of variation across multiple shots hit with the same club, combining both distance and direction into a visual shape (like a circle or oval) that shows shot consistency.

Torque is how much a shaft twists through the swing. Higher torque shafts feel more flexible and generally suit slower swing speeds; lower torque shafts feel stiffer and generally suit faster swing speeds.

Kick point is the section of the shaft that bends most during the swing, influencing trajectory and feel. A higher kick point (closer to the grip) generally produces lower trajectory and a stiffer feel; a lower kick point generally produces higher trajectory and a more flexible feel.
