GolfWRX Launch Report: Mizuno ST-Z 230, ST-X 230 drivers, fairway wood, hybrid
What you need to know: The product of Mizuno’s Speed Technology (ST) Metalwood Project — four years of rapid-fire metalwoods development — 2023 Mizuno ST-Z 230, ST-X 230, and ST-PLTNM feature the centerpiece Cortech Chamber, within which a steel weight is positioned for increased ball speed and spin reduction. The technology extends to the ST-Z 230 fairway wood and hybrid as well.

Mizuno ST-Z 230, ST-X 230: What’s new, key technology
Cortech Chamber: Through slot provides additional COR area by providing sole flex filled with elastomeric TPU material for additional flexure and face stress reduction. Inside the TPU is a stainless steel weight, which is positioned close to the clubface for increased speed and spin reduction. Also contributes to a solid feeling at impact.
SAT 2041 Forged Beta Titanium Face: More flexible and stronger than 6-4 titanium.

Additional model details
ST-Z 230

- Billed as a “straight, stable, and low spinning” driver. Designed for stability on off-center hits.
- Engineers focused on positioning CG location being as close as possible to the Z-axis or neutral axis for lower spin, straight performance, and higher MOI.
- Forged SAT 2041 Beta Ti face, aided by the Cortech Chamber, enhances ball speed and reduces spin
- 14-gram back weight
- Shallower CG for a more penetrating ball flight
ST-X 230

- Billed as a “more workable, mild draw-biased” driver
- Higher spinning, higher launching than ST-Z 230
- Deeper CG and shorter CG distance for a balance of workability in both directions
- 14-gram heel weight
- Toe side composite for shorter CG to shaft axis distance
- More rounded, deeper profile
ST-X PLTNM 230
- An ultra lightweight driver for slower swing speeds
- High launching
- Draw biased
- The ST-X PLTNM is 30g lighter overall than any possible custom option of the ST-X 230
- High spec Helium Platinum Shaft and lightweight grip
What Mizuno says
“Our player testing over the years shows that placing extra weight close to the face results in faster ball speeds and low spin rates,” says David Llewellyn, Director of R&D for Mizuno. “We’ve been steadily working towards the CORTECH Chamber, which is incredibly effective at that job. Encasing the steel weight within the TPU Chamber means that we’re moving weight close to the face at the same time as creating an additional source of energy. Steel is twice the density of Titanium but won’t weld directly, which is where the TPU has a second role.”

Tour Edge unveils all-new Exotics mini driver
Tour Edge Golf has today introduced the all-new Exotics mini driver, engineered to deliver a powerful combination of speed, control, and versatility in the long game.
The Exotics Mini combines a titanium face with a stainless-steel body in design to balance ball speed with stability and control, creating a versatile option at the top end of the bag.

At the core of the design is Tour Edge’s proprietary Combo Brazing technology, a high-precision thermal bonding process that seamlessly fuses a titanium cup face to a stainless-steel body into a single, continuous structure. By eliminating energy loss found in traditional multi-piece constructions, Combo Brazing is designed to deliver faster face response, more efficient energy transfer, and a uniquely powerful yet controlled feel.

The multi-material construction also allows mass to be positioned lower and deeper in the head in a bid to increase stability, while the thin titanium face is engineered to maintain ball speed across a wider impact area.

“While the initial goal was to enhance control and versatility in the long game, Combo Brazing ultimately drove measurable gains in ball speed and distance within the mini driver category. In robot testing, we’ve documented higher ball speeds, higher launch, reduced spin, and increased carry and total distance compared to leading models.” – Vice President of R&D Matt Neeley

In addition to distance performance, the Exotics mini emphasizes forgiveness through a heavier stainless-steel body that shifts mass toward the perimeter. This configuration increases MOI relative to traditional all-titanium mini drivers, helping preserve ball speed and directional stability on off-center strikes. Paired with Pyramid Face Technology from the Exotics metalwood line, the design is intended to support consistent speed across the face.

To further enhance MOI, a lightweight carbon fiber crown frees additional mass that is strategically repositioned low and deep in the head in design to improve stability and promote optimal launch with controlled spin.

“We designed the Mini to be about five millimeters shallower than other mini drivers on the market. That change improves playability off the deck. From a clean fairway lie, it can function as a strong 3-wood alternative while still providing control off the tee.” – Tour Edge CEO David Glod
An adjustable hosel system allows for loft and lie tuning to dial in trajectory and shot shape, while a fixed 13-gram rear weight helps stabilize the head through impact to improve dispersion consistency. The Exotics Mini Driver is available in 11.5 and 13.5-degree lofts in right-handed models.

Pricing & Availability
The Exotics Mini Driver is available for pre-order beginning today for $399.99 USD at touredge.com, and will be available for purchase at retail outlets worldwide on May 22, 2026.

Srixon ZXi combo or TaylorMade P7CB/770 combo? – GolfWRXers discuss
In our forums, our members have been pitting a Srixon ZXi combo against a TaylorMade P7CB/770 combo. WRXer ‘edutch22’ is on the hunt for a new set of irons and kicks off the thread saying:
“Looking at picking up a new set of irons and think I’ve narrowed it down to Srixon ZXi combo or Taylormade P7CB/770 combo. I am currently a 5 cap and allbeit I feel irons are my weakness. My miss is a little to the toe side. I am decently steep at 4-5 down. Always thought I am high spin but recently on trackman my 7 was spinning at 5800 roughly.
My question or looking for thoughts on which one would benefit me more from a forgiveness standpoint? Or is there another iron is should be looking at entirely? I only get to play about once or twice a week, if I am not playing a 2-3 day event. Thanks in advance.”
And our members have been sharing their thoughts and suggestions in response.
Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.
- manima1: “You just can’t go wrong with Srixon ZXi7.”
- MattM97: “You have to hit them to know, the V-Sole on the Srixon can be make or break for many.”
- dmeeksDC: “P7CB is more forgiving for me than ZXi7 because my main miss is low middle and the P7CB still flies and spins great on that miss. These are both really nice irons but I like the P7CB more than the Zxi7 and the P770 (or P790) more than the Zxi5. The Srixons are larger so if that gives you confidence that is the way to go. I don’t feel like I get any benefit from the V-sole and the P7CBs live up to their high Maltby forgiveness rating so the TaylorMades have been great for me.”

Fairways & hybrids are looking good. Shaft options are super limited – I guess that’s a payoff for a less than premium price point. Heads up to anybody that plans on building a separate shaft – Mizuno’s adapter has an off-center bore. If you find an adapter, it will look defective – that’s the design.

Maybe the best looking hybrid I’ve ever seen

Drivers from the different manufacturers all have similar designs.
