Stiff flex and regular flex are the two most common golf shafts used by amateur players and professionals. If you're wondering which one is right, the answer depends on your swing speed, experience level, and critical factors. We'll break down the differences between stiff vs. regular flex golf shafts to help you find the right one for your game and set you up for soaring drives instead of disappointing duffs.

Stiff vs. Regular Flex: What's the Difference?

The main difference between a regular vs. stiff shaft is their flexibility and how they respond to your swing. Stiff flex shafts are less flexible and better suited for golfers with faster swing speeds, typically around 90 to 105 mph. On the other hand, regular flex shafts are more flexible. They can accommodate golfers with average swing speeds, roughly between 80 and 95 mph.

Other key differences between the two include:

Distance and Control

Stiff shafts minimize missed shots and provide greater control and accuracy for golfers with above-average swing speeds. 

Regular shafts offer a balance of distance and control for golfers with moderate swing speeds, allowing them to achieve consistent shots without excessive twisting or torque.

Ball Flight and Spin

Stiff shafts generally produce a more moderate ball flight and less spin than regular shafts. This can be advantageous for golfers with faster swing speeds who want to minimize the impact of wind or other adverse conditions. 

In contrast, regular shafts typically generate higher ball flight and more spin, helping players achieve higher trajectories and increased stopping power on the fairway.

Feel and Sensation

Stiff flex shafts offer a firmer and more responsive feel at impact, providing better feedback to the golfer. 

With their increased flex, regular flex shafts can provide a softer and more dampened feel, which some golfers may prefer for enhanced comfort and feedback.

Swing Tempo

Stiff flex shafts are generally more suitable for golfers with a fast-swing tempo, as they can handle the increased force and provide better control. 

In contrast, regular flex shafts are better suited for golfers with a slower, smoother swing tempo. They allow for more effortless loading and increased clubhead speed.

Golf shafts come in various flexes to accommodate the unique swing characteristics of different golfers. The main types of shaft flex include:

Extra Stiff Shaft

Extra Stiff (X) golf shafts are tailored for golfers with extremely high swing speeds, typically above 105 mph. These shafts offer the highest level of stiffness among all flex categories, ensuring maximum control and stability throughout the swing. For golfers who generate high clubhead speeds, an extra stiff shaft helps maintain accuracy. It minimizes twisting or torque that can result in off-center shots. Notably, Rory McIlroy uses extra stiff shafts in his driver and woods to match his high swing speeds and maintain precision.

Stiff Shaft

Stiff (S) golf shafts are intended for players with above-average swing speeds, typically 90 to 105 mph. These shafts offer less flex than regular flex shafts, providing improved control and stability for golfers who can generate higher clubhead speeds. Tiger Woods has used stiff shafts in his driver and woods throughout his career.

Regular Shaft

Regular (R) golf shafts are intended for golfers with average swing speeds, typically 80 to 95 mph. These shafts are more flexible than stiff and extra stiff shafts, providing a balanced mix of control and distance for players who do not generate very high clubhead speeds. The increased flex in regular shafts helps to transfer more energy to the ball at impact, resulting in greater distance, particularly for those with moderate swing speeds. Regular shafts are aimed at beginners or casual players rather than professional golfers.

Senior Shaft

Senior (A) golf shafts, also referred to as "A-flex" or "amateur" shafts, are designed for golfers with slower swing speeds, typically below 80 mph. These shafts are more flexible than regular, stiff, and extra-stiff shafts, providing greater forgiveness and distance for players with less strength or power in their swings. Senior shafts are especially popular among senior golfers seeking enhanced performance and ease of play.

Ladies Shaft

Ladies (L) golf shafts are tailored for female golfers or those with very slow swing speeds, typically below 70 mph. These shafts offer the highest level of flexibility among all shaft categories, ensuring maximum forgiveness and distance for players with less strength or power in their swings.

Junior Shaft

A junior golf shaft is specifically crafted for younger and smaller golfers, typically aged 5 to 13. These shafts accommodate junior golfers' size, strength, and skill level. Using the right junior golf shaft is crucial for young players to build a solid skill foundation, develop proper swing habits, and enjoy the game fully.

How To Choose Between Stiff Flex vs. Regular Flex

Choosing the right shaft flex—stiff or regular—depends on your swing speed, tempo, and skill level. 

• Swing Speed: If your swing speed is fast, typically above 90 mph, a stiff flex shaft is likely the better choice as it offers greater control. Conversely, a regular flex shaft can provide additional distance and better performance if your swing speed is moderate.

• Swing Tempo and Skill Level: A faster, more aggressive swing tempo benefits from the rigidity of a stiff flex shaft, while a smoother, slower tempo may find a regular flex shaft more forgiving and easier to handle.

• Testing and Feedback: To determine which shaft suits you best, test stiff and regular flex shafts. Filming your shots and seeking feedback from advanced players or golf instructors can be invaluable. They can offer technical advice on your swing, posture, grip, and timing and may identify issues like misalignment or subtle swing flaws that aren't immediately apparent.

By considering these factors and actively testing different flex options, you can find the shaft that best compliments your game and enhances your performance on the course.
