Frequently Asked Questions
What shaft flex do I need?
Shaft flex is primarily determined by swing speed. Under 75 mph: Senior (A). 75-88 mph: Regular (R). 88-100 mph: Stiff (S). Over 100 mph: X-Stiff (X). Tempo matters too - an aggressive tempo player often benefits from a stiffer flex than their speed alone suggests.
What is kick point and how does it affect ball flight?
Kick point (or flex point) is where the shaft bends most during the swing. A low kick point launches the ball higher and is ideal for players who struggle with launch. A high kick point produces a lower, more penetrating ball flight with more control - preferred by better players and faster swingers.
Does shaft weight matter?
Yes. Heavier shafts (70g+ in driver, 110g+ in irons) provide more control and are suited for faster, stronger swingers. Lighter shafts (45-55g driver, 60-80g graphite iron) help slower swingers generate more speed and distance. Most amateurs benefit from lighter shafts than they think.
Iron shafts: steel vs. graphite?
Steel iron shafts (95-130g) are standard for most golfers - they're more consistent and less expensive. Graphite iron shafts (60-90g) benefit seniors and slower swingers who need the extra distance. Many modern graphite iron shafts perform comparably to steel and can reduce vibration for players with arm or wrist issues.
