Mizuno ST-Max 230 driver: High-MOI addition to the ST 230 lineup

Published

on

The new Mizuno ST-Max 230 is joining Mizuno’s ST 230 series of drivers. According to the company, it is a “low-profile, wide-footprint driver.” Given that billing, GolfWRXers will know the company is offering its answer to the “give me MOI, but distance, too” request OEMs have been paying particular attention to as of late with a formula of larger profile (high MOI), lightweight crown (low CG/ease of launch), and a tuned, tech-infused face (distance).

Shallower and longer from heel to toe, the 460cc head is stretched further than any previous Mizuno driver. Here, a picture is worth 1,000 words.

Mizuno makes use of the 40-percent larger, single-piece sole by expanding its face-flexing Cortech chamber in the ST-Max 230. In addition to being longer, the chamber is positioned closer to the face for greater ball speed over a wider area.

Weight savings also allowed engineers to incorporate a 54-gram back weight into the design for greater stability, which is 20 grams more than the ST-X is outfitted with.

Another important puzzle piece, Mizuno’s beta-rich Ti-LFS face features 9 percent greater tensile strength than what the company previously relied on in the ST-Z and ST-X drivers. It’s a better canvas for a multi-thickness face, which Mizuno engineers happily incorporated, allowing them to deliver better ball speed across the face.

Finally, thanks to the ST-Max 230’s forgiveness, engineers have extended the stock shaft length to 45.75 inches to aid golfers in swinging the club faster.

Mizuno ST-Max 230: Pricing, specs, availability

  • Price: $500

Mizuno ST-Max 230 fairway wood

In addition, Mizuno announced the high-trajectory, mid-spin ST-Max 230 fairway wood, which features a larger footprint and lower profile than the ST-Z 230 for ease of launch and forgiveness. The club offers the largest sweet spot for a fairway wood in company history, which is buttressed by a multi-thickness face. The Cortech Chamber is again a fixture. Like with the Max driver, the slot is larger and closer to the face. Additionally, the composite carbon crown is larger, allowing engineers to move more weight around the club.

Full specs below.

Mizuno ST-Max 230 hybrid

Finally, Mizuno within the new “Max,” family, Mizuno announced the new ST-Max 230 hybrid, which, again, features a lower profile and larger profile than the ST-Z 230 hybrid. The Cortech Chamber is larger here as well, providing the same benefits as in the fairway wood. Also like the ST-Max 230 fairway wood, the sweet spot is the largest Mizuno has offered in a hybrid. A waffle crown allows for lower CG, and the company’s “speed bevel” treatment of the leading edge of the club enhances turf interaction.

Project X Denali Blue, Black shaft Review – Club Junkie Review

Published

on

Originally, Project X was known for low-spin steel iron shafts. However, the company might now be known for wood shafts. Denali is the newest line of graphite shafts from Project X. With the Denali line, the company focuses on feel as well as performance.

There are two profiles in the Denali line, Blue and Black, to fit different launch windows. Denali Blue is the mid-launch and mid-spin profile for players who are looking for a little added launch and Denali Black is designed for low-launch and low-spin. Both models are going to offer you a smooth feel and accuracy.

For a full in-depth review check out the Club Junkie podcast on all podcast streaming platforms and on YouTube.

Project X Denali Blue

I typically fit better into mid-launch shafts, as I don’t hit a very high ball so the Denali Blue was the model I was more excited to try. Out of the box, the shaft looks great and from a distance, it is almost hard to tell the dark blue from the Denali Black. With a logo down install of the shaft, you don’t have anything to distract your eyes, just a clean look with the transition from the white and silver handle section to the dark navy mid and tip.

Out on the course, the Blue offers a very smooth feel that gives you a good kick at impact. The shaft loads easily and you can feel the slightly softer handle section compared to the HZRDUS lineup. This gives the shaft a really good feel of it loading on the transition to the downswing, and as your hands get to impact, the Denali Blue keeps going for a nice, strong kick.

Denali Blue is easy to square up at impact and even turn over to hit it straight or just little draws and most of the flex of the shaft feels like it happens right around where the paint changes from silver to blue. The Blue launches easily and produces what I consider a true mid-flight with the driver. While it is listed as mid-spin, I never noticed any type of rise in my drives. Drives that I didn’t hit perfectly were met with good stability and a ball that stayed online well.

Project X Denali Black

When you hold the Denali Black in your hands you can tell it is a more stout shaft compared to its Blue sibling by just trying to bend it. While the handle feels close to the Blue in terms of stiffness, you can tell the tip is much stiffer when you swing it.

Denali Black definitely takes a little more power to load it but the shaft is still smooth and doesn’t give you any harsh vibrations. Where the Blue kicks hard at impact, the Black holds on a little and feels like keeps you in control even on swings that you try and put a little extra effort into. The stiff tip section also makes it a little harder to square up at impact and for some players could take away a little of the draw from their shot.

Launch is lower and more penetrating compared to the Blue and produces a boring, flat trajectory. Shots into the wind don’t rise or spin up, proving that the spin stays down. Like its mid-launch sibling, the Black is very stable and mishits and keeps the ball on a straighter line. Shots low off the face don’t get very high up in the air, but the low spin properties get the ball out there farther than you would expect. For being such a stout shaft, the feel is very good, and the Denali Black does keep harsh vibrations from your hands.

Overall the Project X Denali Blue and Black are great additions to the line of popular wood shafts. If you are looking for good feel and solid performance the Denali line is worth trying out with your swing. Choose Blue for mid-launch and mid-spin or Black for lower launch and low spin.

What we know about Bryson DeChambeau’s 3D-printed Avoda irons

Published

on

Bryson DeChambeau fired an opening-round 7-under 65 at Augusta National, hitting an impressive 15 of 18 greens in regulation in the process. Golf’s mad scientist’s play grabbed headlines and so too did his equipment. In place of the Ping i230 irons he had in the bag last week for LIV Golf’s Miami event, DeChambeau is gaming a prototype 5-PW set of irons from little-known direct-to-consumer manufacturer Avoda.

What is Avoda Golf?

Founded by Tom Bailey, also a Mike Schy student like Bryson DeChambeau, Avoda Golf is a direct-to-consumer golf equipment company that currently manufactures both single and variable-length irons in one model that are available for pre-order.

What irons is Bryson DeChambeau playing?

Per multiple reports, DeChambeau is playing a custom-designed set of single-length irons that incorporate bulge and roll into the face design. The two-piece 3D-printed irons were reportedly only approved for play by the USGA this week, according to Golfweek’s Adam Schupak.

Regarding the irons, DeChambeau told Golf Channel the irons’ performance on mishits was the determining factor in putting them in play this week. “When I mishit on the toe or the heel,” DeChambeau said. “It seems to fly a lot straighter for me and that’s what has allowed me to be more comfortable over the ball.”

What can we tell about the design of the clubs?

These days, it is a little hard to speculate on what is under the hood with so many hollow body irons. DeChambeau’s irons look to be hollow on the lower section as they do flare back a decent amount. That “muscle” on the back also looks to be fairly low on the iron head, but we can assume that is progressive through the set, moving up higher in the short irons.

A screw out on the toe is probably used to seal up the hollow cavity and used as a weight to dial in the swing weight of the club. From pictures, it is hard to tell but the sole looks to have a little curve from heel to toe while also having some sharper angles on them. A more boxy and sharper toe section looks to be the design that suits Bryson’s eye based on the irons he has gravitated toward recently.

What are bulge and roll, again?

Two types of curvature in a club face, traditionally incorporated only in wood design. Bulge is heel-toe curvature. Roll is crown-sole curvature. Both design elements are designed to mitigate gear effect on off-center strikes and produce shots that finish closer to the intended target line. (GolfTec has an excellent overview of bulge and roll with some handy GIFs for the visual learner)

What else is in DeChambeau’s bag?

Accompanying his traditional Sik putter, Bryson builds his set with a Ping Glide 4.0 wedges, a Krank Formula Fire driver and 5-wood, and a TaylorMade BRNR Mini Driver, all with LA Golf graphite shafts.
