As the lead golf instructor at Tell Me More Golf, I’ve had the opportunity to test and analyze a multitude of golf shafts. The Project X and Project X LZ shafts stand out for their unique features and performance.

This shaft review will examine these two popular shafts, their design specs, technology, and how they cater to different swing speeds and styles.

Whether you’re a seasoned golfer or a beginner looking to upgrade your gear, this comparison will provide valuable insights to help you make an informed decision.

So, let’s dive in and explore the world of Project X LZ vs Project X.

Project X LZ vs. Project X Golf Shafts Compared

Several factors come into play when comparing Project X LZ vs.Project X Golf Shafts. Both shafts are renowned for their advanced technology and high performance, making them popular among golfers, from beginners to PGA tour pros.

The Project X LZ shaft is known for its unique “Loading Zone” technology. This design reduces stiffness in the midsection while maintaining robustness in the butt and tip sections, leading to a smooth feel and efficient energy transfer during the downswing, providing higher ball speeds. 

This feature, coupled with its mid-launch trajectory and low spin, makes the LZ shafts versatile and suitable for a wide range of golfers.

On the other hand, the standard Project X shafts are designed for players with fast swing speeds seeking maximum distance and control.

They maintain a stout profile throughout the entire shaft, providing a flat, penetrating ball flight and unmatched stability. These shafts are often the preferred choice for stronger swingers.

Both shafts come in various flex options, catering to different swing speeds and styles. However, the Project X LZ steel iron shafts are generally considered more player-friendly due to their less demanding profile and increased responsiveness.

In terms of brands, both shafts hold their own against other popular brands like:

• Modus
• True Temper/AMT
• Nippon
• Dynamic Gold
• KBS Tour
• HZRDUS

You’ll find Project X and Project X LZ as options in premium irons made by manufacturers like:

• Callaway
• Ping
• Titleist
• Mizuno
• PXG
• TaylorMade
• Srixon

However, the choice between Project X LZ and Project X, or any other brand, ultimately depends on the individual golfer’s swing characteristics and personal preferences.

Project X shafts are used frequently on the PGA Tour by players like Jordan Spieth and John Rahm.

Project X LZ Pros And Cons

The Project X LZ golf shaft is a popular choice among golfers for its unique blend of performance and feel.

However, the Project X LZ shaft has its cons. Some golfers may find the feel of the shaft too stiff or harsh, which may not be suitable for players who prefer a different trajectory.

Additionally, the shaft’s higher price point may deter some golfers with a range from $40 to $65 per shaft.

Shaft Weight

Depending on the flex, the Project X LZ shaft comes in various weights, ranging from 110g to 125g. This range of weights caters to a broad spectrum of golfers, allowing them to choose a shaft that matches their swing speed and style.

However, it’s important to note that the weight of the shaft can significantly affect its performance.

A lighter shaft can help increase swing speed, while a heavier shaft can provide more control and stability.

Therefore, golfers should consider their swing characteristics and personal preferences when choosing the weight of their Project X LZ shaft.

Swing Speed

The Project X LZ iron shaft is designed to cater to a broad range of swing speeds, thanks to its unique “Loading Zone” technology.

This technology reduces stiffness in the midsection of the shaft, allowing for efficient energy transfer and a smooth feel during the downswing. This design produces a shaft that can adapt to various swing speeds, providing optimal performance for a wide range of golfers.

However, it’s important to note that the swing speed that a golfer can achieve with the Project X LZ shaft also depends on other factors, such as the golfer’s strength, technique, and the shaft’s weight and flex.

Therefore, while the Project X LZ shaft is versatile, golfers should still ensure that it matches their swing characteristics for the best results.

Flex

The Project X LZ golf shaft offers a unique blend of flexibility options that cater to a wide range of golfers. The shaft comes in four different shaft flexes: 5.0 (R flex), 5.5 (R+ flex), 6.0 (S flex), and 6.5 (S+ flex).

This range of flexes allows golfers to choose a shaft that matches their swing speed and style, leading to optimal performance on the course.

One of the key features of the Project X LZ shaft is its “Loading Zone” technology.

This design reduces stiffness in the midsection while maintaining robustness in the butt and tip sections.

This results in a shaft loading more efficiently during the downswing, leading to efficient energy transfer and a smooth feel.

Project X Pros And Cons

Project X golf shafts are renowned for their superior performance and accuracy, making them popular among high-level golfers. 

The shafts are consistently praised for providing reliable results with each swing. Additionally, the Project X lineup offers a wide range of models, allowing golfers to choose a shaft that best suits their swing speed and style.

However, Project X shafts also have their cons.

They come with a higher price point at $40 to $60 per shaft, which may deter some golfers. 

They may also be unsuitable for players who prefer a different feel or trajectory. Lastly, there is limited availability in some regions.

Shaft Weight

Project X golf shafts are celebrated for their precision and performance, with weight playing a significant role. The weight of a shaft greatly influences swing speed, ball flight, and overall club feel. Project X shafts offer a spectrum of weights to cater to various golfers.

For instance, the Project X 6.0 shaft weighs around 120 grams, balancing control and power. 

On the other hand, the heavier Project X 7.0 shaft, weighing approximately 130 grams, is designed for golfers with faster swing speeds, offering lower spin and a low launch.

These weight options allow golfers to choose a shaft that best suits their swing characteristics and game style.

Swing Speed

Project X golf shafts are designed to cater to various higher swing speeds, offering a range of models to suit different players.

For instance, the Project X 6.0 shaft is ideal for golfers with a swing speed of around 105-115 mph, balancing control, and power. On the other hand, the heavier Project X 7.0 shaft is designed for golfers with faster swing speeds of around 115 mph and above, offering lower spin and a more penetrating ball flight.

These options allow golfers to choose a shaft that best suits their clubhead speed, leading to optimal performance on the course.

Flex

Project X golf shafts are known for their distinct flex options, catering to a wide range of golfers.

The flex of a shaft is crucial as it influences the ball’s trajectory, control, and speed.

Project X shafts, like Project X LZ, are somewhat unique in their flex rating system, using numbers instead of traditional labels. For instance, a 5.0 flex is equivalent to a regular flex, while a 6.0 and 6.5 flex are comparable to stiff and extra stiff flexes.

This system allows for more precise tuning to match a golfer’s swing speed and style, enhancing performance on the course.

Conclusion

In golf, the choice of the shaft can significantly impact your game. When comparing Project X LZ and Project X shafts, it’s clear that both offer unique advantages.

With their Loading Zone technology and softer midsection, the Project X LZ shafts provide a smooth feel and increased energy transfer, making them a popular choice for a wide range of golfers.

On the other hand, Project X shafts are known for their precision and consistency, catering to high-level golfers with fast swing speeds.

Choosing between Project X LZ and Project X will ultimately depend on your playing style, swing speed, and performance goals.
