Mizuno ST-X 230 Driver Review

In a market filled with compelling driver stories, Mizuno has introduced an intriguing narrative with their ST-X 230 driver. By combining seemingly contradictory characteristics – “more workable” and “draw biased” – they’ve created a unique offering that deserves close attention.

Design and Aesthetics

The ST-X 230 breaks the mold of typical draw-biased drivers with its traditional appearance. The head features a round, full shape with only the subtlest heel-side bias. Its face height runs slightly taller than average, while the front-to-back length remains conventional. The carbon fiber crown element is positioned well back from the leading edge, minimizing visual distraction at address.

Comparing it to its sibling, the ST-Z 230, reveals surprisingly similar address profiles. While the ST-X features a slightly more closed face angle in neutral settings, the difference is minimal. The real distinction becomes apparent on the sole, where the ST-X positions its weight closer to the heel for draw bias, contrasting with the ST-Z’s centered weight placement.

Sound and Feel

Impact feedback proves both sophisticated and informative. Center strikes produce a satisfying low-pitched “pop” complemented by gentle metallic overtones. The sensation through the hands feels lively and dynamic, creating an impression of energetic rebound off the face.

While the driver offers good forgiveness on mishits, it doesn’t mask poor contact. Off-center strikes produce a notably duller feel and sound, providing clear feedback without being harsh. This honest feedback system will appeal to players who appreciate knowing exactly where they’re striking the ball.

Performance Dynamics

Perhaps the most interesting aspect of the ST-X 230 is its dual personality. The driver has found its way into tour bags – notably those of Greyson Sigg and Ben Griffin – while remaining accessible to higher handicap players. This versatility stems from several key features:

CORTECH Chamber Technology

• Maintains consistently low spin rates
• Enhances feel at impact
• Promotes stable ball speeds across the face

Carbon Sole Construction

• Enables strategic weight placement
• Enhances overall stability
• Improves forgiveness on mishits

Shaft Configuration Impact

The ST-X 230’s personality can shift significantly based on shaft selection. With the stock lightweight options (sub-60 grams), which tend to be more active, the driver’s draw bias becomes more pronounced. Testing with the Kai’li Blue shaft showed a natural tendency for shots to start left and draw.

Conversely, installing a stiffer, heavier shaft can unlock the driver’s workable characteristics. The shorter shaft-to-CG distance potentially offers better players more face control. Mizuno accommodates this versatility with numerous custom shaft options.

PLTNM Version

For players seeking maximum draw bias and launch assistance, Mizuno offers the ST-X PLTNM 230 variant. This specialized build features:

• Ultra-light 40-gram shaft options
• Available in 10.5° or 12° lofts
• Enhanced draw bias characteristics
• Optimized for slower swing speeds

Frequently Asked Questions

Q: Is this primarily a game improvement driver or a better player’s club?
