Mizuno ST-Z 230

Reviewer testing: the head particularly impressed on off-centre strikes, with the ball rarely falling off line despite hitting off the toe — in indoor testing only one ball finished more than ten yards from the desired target line. The internal stabilising chamber provides additional sole flex to improve ball-speed retention on impact. The carbon composite crown lowers CG for higher MOI. However, independent robot testing places the head 27th overall with scores for accuracy and forgiveness finishing towards the bottom of those scoring categories — a stark divergence between reviewer testing (excellent off-centre retention) and robot testing (poor accuracy/forgiveness). Net above-average forgiveness in reviewer hands but data-test-poor in lab conditions.

Reviewer testing measured a 152 mph ball-speed average — premium for a 2023 fairway. Independent robot testing's Most Wanted ranking: 14th overall in distance — top-quartile in the 2023 fairway field. The 3rd-generation maraging steel face hits 1.6mm thickness — the thinnest face ever on a Mizuno fairway wood. The internal stabilising chamber adds energy return at impact for ball-speed support. Top-tier 2023 distance — among the best independent robot-tested categories for the head.

Reviewer testing: the head is the straightest 3-wood for 2023 — neutral CG, no imposed bias. Industry coverage: straight, stable and high launching — workable but defaults to straight. The centered CG on the Z-axis is engineered for neutral trajectory rather than draw or fade bias. 4° hosel range (13-20° effective via 15°/18° heads) lets skilled players dial in trajectory. Above-average workability for a high-MOI fairway — neutral CG plus shape-on-demand intent, even if straight is the default ball flight.

Reviewer testing: the feel on centre is powerful and explosive. Industry coverage: delivers a powerful, solid sensation at impact. The internal stabilising chamber's stainless-steel mass in elastomer creates more energy return, whilst moving weight closer to the clubface to reduce spin, and produce a more solid feel at impact. Off-centre feedback degrades quickly — when you miss the sweet spot, your hands will feel the strike location and a very dull impact. Above-average centred feel; informative-but-harsh off-centre feedback.

Reviewer testing: on centre, this club produces a mid-low pitched pop without any metallic notes. Leave the centre of the face, and the sound quickly turns to a dull thud. Reviewer testing highlighted awesome sound as a key pro. The internal stabilising chamber dampens unwanted vibrations that negatively impact the sound. Same on-centre / off-centre acoustic divergence as the 2021 ST-Z and 2022 ST-Z 220 — clean centred pop, dull off-centre thud. Above-average centred acoustic; informative off-centre.

Reviewer testing: classic gloss black carbon crown that frames the ball perfectly at address — great address look that will appeal to a wide variety of players. Industry coverage: full, round shape, compact and player-ish appearance that gives an overall midsized impression. Industry awards 2023 Gold panel: the fairways likely fit a better player's eye, but they neatly hide the elements that allow them to play with the additional forgiveness average golfers need. Top-decile aesthetic for the 2023 fairway field — the head's strongest dimension.
