GolfWRX Launch Report: 2023 Callaway Paradym drivers



What you need to know: An almost completely carbon fiber body is the “paradigm shift” of Callaway’s Paradym driver (360° Carbon Chassis). Eliminating titanium from the body of the club allowed engineers to distribute weight in a manner that “breaks the tradeoff between incredible distance and exceptional forgiveness,” according to the company. There are three models in the family: Paradym (designed for the broadest group of golfers), Paradym X (draw biased), Paradym Triple Diamond (compact, lowest spinning, lowest launching, fade biased).

2023 Callaway Paradym drivers: What’s new, key technology

  • Industry-First 360° Carbon Chassis: Allows for “unprecedented weight redistribution for maximized distance.” The combination of the Triaxial Carbon Crown and Forged Carbon Sole are 45 percent lighter than a titanium chassis allowing weight to be pushed forward (promoting ball speed) and back (higher MOI) in the clubhead.
  • New Jailbreak A.I.: The latest iteration of A.I. designed Jailbreak is 33-percent lighter and provides both horizontal and torsional stability.
  • New A.I Designed Face: Focused on downrange dispersion, Paradym features an improved A.I. designed face.
  • Face Cup and Forged Titanium Face: The first Callaway driver to feature Face Cup technology, which is joined with a titanium face for improved energy transfer to the golf ball.

Additional model details

Paradym: With high MOI and adjustable perimeter weighting, Paradym fits the largest segment of the fitting bell curve. High launch, low spin, neutral ball flight.

Paradym X: Draw-biased, high-launching, high-MOI driver. Larger profile. Most forgiving driver in the lineup.

Paradym Triple Diamond: Low spin, low launch. Slightly smaller (450 cc) profile). Paradym is designed for the better player who is looking to work the ball. Neutral bias.

What Callaway says

Evan Gibbs, Callaway’s R&D Woods Director, gave this overview of the Paradym technology:

“The 360° Carbon Chassis really refers to the center portion of the driver that’s made completely of carbon composite. Two proprietary materials to Callaway, on the top we have a Triaxial Carbon Crown, it’s a continuous carbon fiber that’s woven and creates a very thin lightweight structure. And then in the bottom, we have a Forged Carbon which consists of bundles of chopped fibers that are forged into shape.

“This gives us an advantage over traditional composites and allows us to mold it into some complex geometries and gives a lot better control of the thickness of the part. So we can strategically thicken and thin it out where it needs to be in order to get the right strength and stiffness. It’s a big advantage because it takes out all the metal in the middle portion of the clubhead.

“There’s no titanium or aluminum reinforcements, this is 100% carbon composite bonded together, and it’s about 44% lighter than a Titanium chassis, so that gives us a ton of discretionary weight that we can take out of the middle of the clubhead and move into different areas to enhance performance. A lot of it is in the back of the clubhead to give some adjustability and higher MOI, and some of it shifted to the front to enhance the ball speed technologies.”

    These aren’t $600 for all models are they? I heard $725 street price with any of the actually good shafts. Hope I am wrong. $600 is insane as-is.

    New Tech is not necessarily better tech. Let’s have somebody (Callaway should do this) give us a comparison of distance and dispersion with this $600 extravagance compared to last year’s model. Impress me with performance not tech.

    I’m super excited that Callaway is really pushing the boundaries of what is possible, and doing exactly what Taylormade did last year.

‘Engineered for extreme backspin’ – Mizuno unveils new S23 wedges



Mizuno has today unveiled its new S23 wedges, which the manufacturer says are “comprehensively engineered for extreme backspin.”

The wedges are designed to combine the precision and playing profile of a player’s bladed wedge with the aggressive performance of a toe-weighted design and feature a centralized sweet spot for maximum control.

The S23 wedges showcase a shorter hosel and a heel-orientated cavity allowing greater mass to be pushed towards the toe. This creates a centred sweet spot, as opposed to a heel-side location in conventional wedges. 

The centred sweet spot is designed to contribute to longer impact time, less head deflection and higher spin from both full and partial shots.

“That check and spin you see from the pros isn’t purely because of newer grooves – most of us don’t have the consistency of strike to get that kind of action. For the vast majority, a centralised sweet spot makes it much easier to find and get that repetitive action.” – David Llewellyn, Director of R&D for Mizuno

The S23 wedges are One-piece Grain Flow Forged HD at Mizuno’s facility in Hiroshima, Japan – where Mizuno irons have been produced since 1968. They have a Tour-ready design with a player’s preferred, versatile look at address. But, with weight pushed to the toe, a partial heel cavity and a short hosel, they offer a centralised sweet spot designed to offer a more consistent strike and reliable high-spin numbers.

The wedges offer a loft-specific profile with stronger lofts featuring a tear-drop straight edge, flowing into a more rounded lob wedge, with grinds to suit throughout.

The precise grooves in the S23 wedges are quad-cut milled and loft specific, cut into Boron infused 1025 mild carbon steel for a longer effective lifespan. In addition, Mizuno’s HydroFlow Micro Grooves are laser etched to release moisture in a bid to reduce spin drop-off in wet conditions.

The S23 wedges come in either a white satin brush chrome or copper cobalt finish and will be in retail from February 2023 at a price of $160 per wedge.

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


  • 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.”

Titleist adds low-bounce T Grind to its Vokey Design SM9 family



Titleist has today added the low-bounce T Grind to its Vokey Design SM9 lineup.

Previously available only as a WedgeWorks custom order, the T Grind will now be widely available in both stock and custom options as an extension to the existing SM9 family, being offered in SM9 58.04T and 60.04T models.

As a low-bounce wedge with a narrow crescent surface and wider back flange, the T grind is designed to allow for shot making under any condition. Compared to the L Grind, SM9’s other low-bounce option, the T Grind features a narrower forward sole and more aggressive heel, toe and trailing edge relief.

“Wedge play is an art, and the T Grind brings out the best in the artist. The leading edge stays low to the playing surface as the wedge is rotated, which allows the golfer to hit a variety of shots from tight lies. This is the wedge that really made Vokey Grinds an important part of our process – and is still a great option to this day.” – Bob Vokey

The new T Grind features a CG that has been raised vertically by adding weight to the topline design, where a tapered pad at the back of the toe helps align the CG properly without being visible from the playing position – promoting a more controlled ball flight and solid contact.

A new Spin Milled cutting process in the SM9 models – which includes tightening our allowable tolerances – produces consistently sharper grooves wedge after wedge in design for a higher, more consistent spin.

Specs, Availability & Pricing

  • Shaft: True Temper Dynamic Gold S200
  • Grip: Golf Pride Tour Velvet 360 White
  • Lofts, Bounce 58.04T RH/LH, 60.04T RH/LH
  • Color Codes: Tour Chrome, Brushed Steel, Jet Black finishes. Raw finish available for custom only.
