Do I Need Stiff Or Regular Flex

Choosing the right golf club flex can dramatically impact your game, preventing slices, hooks, and lost distance. Selecting between stiff and regular flex shafts hinges on your swing speed and tempo, a decision every golfer must face to optimize performance.
This guide offers a concise breakdown to determine the ideal flex for your swing, helping you avoid common mistakes and unlock your potential on the course. We cut through the jargon to deliver practical advice, ensuring you select the best fit for your game immediately.
Decoding Flex: Stiff vs. Regular
The flex of a golf club shaft dictates how much it bends during your swing. A shaft that's too stiff won't load properly, leading to a loss of power and potentially a slice. Conversely, a shaft that's too flexible can cause inconsistency and hooks, especially in faster swings.
Who Needs Stiff Flex?
Stiff flex shafts are designed for golfers with faster swing speeds. Generally, if your driver swing speed exceeds 95 mph, a stiff flex is likely the better choice. This recommendation aligns with data from leading club manufacturers like Callaway and TaylorMade, who conduct extensive swing speed testing.
Think of professionals and lower-handicap players as the target demographic for stiff flex. A faster swing requires a stiffer shaft to maintain control and accuracy at impact.
Who Needs Regular Flex?
Regular flex shafts are the standard for most amateur golfers and those with moderate swing speeds. If your driver swing speed falls between 85 mph and 95 mph, a regular flex is generally recommended. Club fitting experts at Golf Galaxy and PGA Superstore consistently advise players within this range to start with regular flex options.
This flex provides a good balance of control and power for the majority of golfers. It allows for adequate shaft loading without being overly demanding on swing mechanics.
Measuring Your Swing Speed: How to Find Out
Knowing your swing speed is the crucial first step. The most accurate way to determine your swing speed is by using a launch monitor.
Most golf retailers and driving ranges equipped with technology like TrackMan or FlightScope. These devices precisely measure clubhead speed and ball speed, giving you a data-driven understanding of your swing.
Alternative Methods for Estimation
If access to a launch monitor is limited, you can estimate your swing speed based on your average driving distance. A drive of 220-250 yards typically suggests a regular flex is suitable. Greater than 250 yards usually indicates a need for stiffer flex.
However, this method is less accurate than using a launch monitor. Factor in environmental conditions like wind and terrain when making your assessment.
Beyond Swing Speed: Considering Tempo and Feel
While swing speed is the primary factor, tempo and feel also play a role in selecting the correct flex. A golfer with a smooth, controlled swing, even at a higher speed, might benefit from a more flexible shaft. Conversely, an aggressive, quick swing may require a stiffer flex for optimal control.
Experimenting with different flexes during a club fitting session is highly recommended. Pay attention to how the club feels throughout your swing and at impact.
The Importance of Club Fitting
Ultimately, a professional club fitting is the most reliable way to determine the ideal shaft flex for your individual swing. A qualified fitter can analyze your swing data, observe your ball flight, and provide personalized recommendations.
Many golf courses and specialty stores offer club fitting services, often for a fee, but the investment can pay dividends in improved performance and enjoyment of the game.
The Consequences of the Wrong Flex
Using a shaft that’s too stiff can lead to a loss of distance and an increased tendency to slice. The club will feel rigid and unresponsive, making it difficult to load the shaft properly.
Conversely, a shaft that’s too flexible can cause inconsistent shots and hooks. The club will feel whippy and uncontrollable, leading to a loss of accuracy.
