Project X HZRDUS 6.5 RDX Smoke Blue PVD 60g Extra Stiff Flex Driver Shaft

The Project X HZRDUS Smoke RDX Blue PVD 60g 6.5 Extra Stiff Driver Shaft is engineered for powerful golfers seeking exceptional stability, penetrating launch and controlled spin without sacrificing responsive feel.

Combining advanced Hexcel HexTow carbon fibre, a distinctive soft-midsection profile and counterbalanced construction, the Smoke RDX Blue delivers the resistance required for aggressive swings while maintaining a smooth, connected loading sensation. Its striking metallic blue PVD finish completes a premium performance shaft designed for speed, stability and control.

Overview

The Project X HZRDUS Smoke RDX Blue PVD 60 6.5 Extra Stiff combines the stability-focused engineering of the HZRDUS family with a distinctive bend profile designed to provide greater responsiveness during transition.

While many Extra Stiff shafts rely on an extremely rigid overall structure, Smoke RDX Blue takes a different approach.

Its carefully engineered profile combines a firm handle, more responsive midsection and stable tip, creating a shaft that can withstand significant loading while still allowing the golfer to feel it working throughout the swing.

This combination is particularly valuable for golfers with faster swing speeds who prefer a smooth loading sensation rather than an excessively harsh or board-like response.

The construction incorporates Hexcel HexTow carbon fibre, selected to provide strength and structural stability while supporting the distinctive feel of the Smoke RDX Blue platform.

The shaft also features a counterbalanced design, positioning additional mass towards the handle to provide greater flexibility when building drivers with heavier heads or different playing lengths.

In the 60g-class Extra Stiff configuration, these characteristics create a particularly appealing combination of lightweight speed potential and high-speed stability.

Finished in a distinctive metallic blue PVD coating, the result is a driver shaft that combines powerful performance, responsive feel and premium aesthetics.

Performance Overview

The HZRDUS Smoke RDX Blue PVD 60 6.5 is engineered around a low-launch, low-spin performance profile, producing a strong, penetrating trajectory designed for golfers who generate significant clubhead speed.

Its defining characteristic is the relationship between Extra Stiff stability and responsive midsection loading.

During transition, the firm handle provides support as the golfer applies force to the shaft, while the softer midsection allows a noticeable sense of loading without excessive movement.

As the club accelerates towards impact, the stable tip section helps maintain control of the clubhead, supporting predictable launch conditions and consistent directional performance.

The 6.5 Extra Stiff flex provides additional resistance compared with the 6.0 Stiff version, making it particularly suitable for golfers with faster swings or more aggressive transitions.

Importantly, however, the Smoke RDX Blue retains its characteristic smoothness.

Rather than feeling uniformly rigid, the shaft allows stronger players to experience a progressive loading sensation while maintaining the stability required for confident impact.

The 60g-class construction further enhances its versatility, providing a lighter alternative to traditional 70g Extra Stiff shafts without abandoning the control-focused characteristics of HZRDUS.

The result is a shaft that delivers:

• Strong, penetrating low-launch trajectory
• Controlled low-spin performance
• Extra Stiff stability for powerful swings
• Smooth and responsive midsection loading
• Firm handle and stable tip characteristics
• Counterbalanced weight distribution
• Excellent speed potential from the 60g-class profile
• Consistent and predictable dispersion

Key Technologies

Hexcel HexTow Carbon Fibre

The Smoke RDX Blue incorporates Hexcel HexTow carbon fibre, an advanced composite material selected for its strength and performance characteristics.

This construction helps provide the structural stability required for a powerful driver shaft while retaining the responsiveness that distinguishes Smoke RDX Blue from more rigid HZRDUS profiles.

Counterbalanced Design

The counterbalanced profile positions a greater proportion of the shaft's mass towards the grip end.

This helps reduce the swing-weight effect of heavier driver heads and provides additional flexibility when optimising playing length, head weight and overall club balance.

For golfers using modern adjustable drivers, this can be particularly useful when fine-tuning the finished build.

Responsive Midsection

One of the defining characteristics of Smoke RDX Blue is its more responsive midsection.

This allows the shaft to load progressively during transition, creating a smoother sensation than many traditional low-launch Extra Stiff profiles.

Firm Handle and Stable Tip

The combination of a firm handle and stable tip provides structural support at both ends of the shaft.

This helps maintain control during aggressive transitions and through impact while allowing the midsection to deliver the smooth loading sensation associated with Smoke RDX Blue.

Premium Blue PVD Finish

The distinctive Physical Vapour Deposition (PVD) finish gives the shaft its striking metallic blue appearance.

The premium finish provides a distinctive visual identity while retaining the underlying performance characteristics of the Smoke RDX Blue platform.

Player Profile

This shaft is ideally suited to golfers who:

• Have fast to very fast driver swing speeds
• Prefer a 6.5 / Extra Stiff shaft
• Have a strong or aggressive transition
• Generate excessive launch or spin
• Want a penetrating driver trajectory
• Prefer a responsive midsection rather than a uniformly rigid shaft
• Want Extra Stiff stability without moving into a heavier 70g profile
• Play modern driver heads with adjustable weighting
• Want the build flexibility of a counterbalanced shaft
• Value premium materials and a distinctive shaft finish

The 6.5 Extra Stiff flex is particularly appealing to stronger golfers who can consistently load a firmer shaft but still prefer a noticeable sense of responsiveness during transition.

As a general fitting guide, this flex is most likely to suit golfers with driver swing speeds around 105–115 mph or higher, although tempo, transition, release pattern, driver head characteristics and finished playing length should also be considered.

Why Choose the Project X HZRDUS Smoke RDX Blue PVD 60 6.5

The HZRDUS Smoke RDX Blue PVD 60 6.5 is designed for golfers who want Extra Stiff stability without sacrificing the feel of the shaft loading throughout the swing.

That distinction is particularly important for faster players.

At higher swing speeds, a shaft needs sufficient resistance to remain controlled under significant load. However, not every powerful golfer benefits from an extremely rigid profile that provides very little feedback during transition.

Smoke RDX Blue offers a different approach.

Its firm handle and stable tip provide the structural support required for aggressive swings, while the more responsive midsection creates a smoother, more connected sensation.

The 6.5 Extra Stiff flex increases resistance for stronger players, while the 60g-class construction retains the speed potential of a lighter performance shaft.

The counterbalanced design adds another useful dimension, particularly for golfers experimenting with heavier driver heads or custom playing lengths.

Combined with the low-launch, low-spin performance characteristics and premium PVD finish, this creates a shaft that delivers an appealing blend of power, stability, responsiveness and control.

With this shaft, you can expect:

• Strong, penetrating driver flight
• Low launch and controlled spin
• Extra Stiff stability for aggressive transitions
• Smooth, responsive midsection loading
• Excellent control through impact
• Counterbalanced construction for greater club-building flexibility
• Speed potential from the 60g-class profile
• Consistent and predictable ball flight
• Premium HexTow carbon construction
• Distinctive metallic blue PVD finish

This is a premium performance graphite driver shaft for powerful golfers who want to combine the control and resistance of Extra Stiff flex with the smooth-loading characteristics of Smoke RDX Blue — delivering penetrating flight, counterbalanced versatility and dependable stability in one of the most distinctive shafts in the Project X HZRDUS family.
