Mizuno introduces new ST-G 220 driver

Published

on

Mizuno has unveiled its next-generation ST-G 220 driver, which features new adjustability for more precise fitting.

At the core of the new 2021 ST-G 220 driver from Mizuno is shorter lateral weight tracks, which allow for a new center/back weight port.

2021 Mizuno ST-G 220 driver: The details

The combination of three tracks and two moveable weights is designed to allow players to alter the ST-G from ultra-low spinning to a highly playable mid-spinning option, with fade or draw bias in both, depending on preference. 

The evolution to the ST-G 220’s weight locations offers golfers a rare combination of both backspin and fade/draw adjustability options. Traditionally, adjustable drivers have been more effective at just one of those tasks.

The new ST-G 220 is also designed to deliver performance from off-center strikes across each varying weight position.

Speaking on the new driver and its adjustability features, Chris Voshall, golf club engineer at the company, said

“Having that little bit of extra adjustability is especially useful out on tour – where we can fine-tune a player’s flight. Or make an adjustment for a particular tournament when the player doesn’t want the feel of a completely new driver.

“The ST-G 220 has so much more effective movement of weight along both the X and the Z axis. We can set it to be very low spin, a more playable mid spin, heavily fade or draw biased and just about anything in-between.”

The new addition from Mizuno also contains a modern player’s profile, with a deeper face, and shorter back to front look, while still using the full capacity 460cc head size.

A new multi-thickness Cortech Face has been constructed to help allow for the maximum return from Mizuno’s SAT2041 Beta Ti face.

Per Mizuno, SAT2041 stands for Super/Alloy/Titanium/20% Vanadium/4% Aluminum/1% Tin and it offers 17 percent more tensile strength and 8 percent more flexibility than traditional 6-4Ti.

In addition, an optimized Wave Sole is designed to deliver an additional contribution to ball speed from low on the clubface, while the new dual weight center slot allows two central back weights for deeper CG capability in a bid to provide higher stability, launch, and spin.

The driver features four degrees of loft adjustability (7-11 degrees). It will be available at retail on October 14th at a price of $499.95.

    I’m glad I just bought the sub70 849 Pro.

    Will these have the same adapter sleeve as the ST-Z/ST-X?

What really happens during a putter fitting?

Published

on

With all due respect to the flastick, it’s probably safe to say when most golfers envision a club fitting, the last “club” they are thinking about is the putter.

Dial in a driver, optimize your bag setup and gapping, find the right irons and shaft combination — even wedge fittings probably garner more attention.

Should they? Shouldn’t we be paying more attention to making sure the club we use on every hole — with which the margins are the slimmest — is optimal? Shouldn’t the process of putter calibration be more sophisticated than grabbing one off the rack that feels good and you holed a couple of putts with on the equivalent of outdoor carpet?

The team at Club Champion, the nation’s No. 1 club fitter, certainly think so, and they were kind enough to answer a few questions on the subject of putter fitting.

And we’d be remiss if we didn’t mention golfers get their fitting fee waived all September long at Club Champion — a $100 value — this month when they purchase a new putter.

GolfWRX: Why is putter fitting important, first of all?

Club Champion: So many reasons, but the easiest to understand is that the putter is the only club you use on every hole. It’s not a full-swing club so it’s not as sexy as a driver when people think of fitting — you aren’t gaining distance or obvious bragging rights. Instead, you’re dialing in your control on the greens, which is where the most strokes can be saved. For most average players, putts account for 40% of their strokes…there’s a ton of room for error there if your putter isn’t the proper head style, weight, length, and so on.

GolfWRX: What should a golfer bring to a putter fitting?

CC: Their current gamer and an open mind. We find that putters, more often than many other clubs, tend to be an emotional purchase versus a performance-based one. Putters are so stylized and can be so beautiful, so we see a lot of people coming in with preconceived notions about which brands or models they’re dying to have in the bag, but that isn’t always the right option for their stroke. Having an open mind and trusting the SAM PuttLab data is just as important as trusting the numbers in front of you when TrackMan is telling you which driver is the best performer.

GolfWRX: Is a putter fitting done as part of a full-bag fitting, or what is the process?

CC: The putter is included in our full bag fittings and we offer putter fittings as a separate fitting type as well. The best value is to do the whole bag at once but there are plenty of people who want to experience a putter fitting on its own.

GolfWRX: How do the goals of a putter fitting differ from (or are similar to) the full-bag fitting?

CC: At the end of the day, all fittings share the same goal of lowering your scores. A putter fitting is a slightly different approach, in that we use SAM PuttLab technology instead of TrackMan, but we have a similar process — set a baseline with your gamer, use that data to dial in the club specs you need, test your options, recommend the best performer. We’re looking for more control, better feel, consistency and more.

GolfWRX: What is the process for putter fitting?

CC: As stated above, we’re starting with your gamer. We use the SAM PuttLab system to collect dozens of metrics about your stroke with your current putter; everything from your face at impact to your spin to your lie at impact and so on. We then take the data generated by SAM PuttLab to dial in the ideal head style (mallet, blade, etc.) and then we go from there. We’re looking at everything — weight, toe hang, even sightlines and shaft options — to make sure that you’re aiming properly and staying on-line each time.

GolfWRX: In terms of results, what do most golfers see?

CC: There’s no one-size-fits-all result in any fitting, but we usually see a measurable difference in speed control. When your putter looks and feels right, you’re able to better judge distances and the force needed to get the putter to the hole. We also tend to see a correction for common problems — consistent left or right misses and so on.

GolfWRX: If a player likes to switch between putters for different green speeds or has a few putters in rotation, what do you suggest s/he does?

CC: We don’t see this often, but we always try to dial in the basics like length and grip size so there’s consistency across all options. Then, we take a look at their specific uses for each putter and work on tweaking the other elements to best suit those uses.

GolfWRX: How often should a player be fit for a putter? Is it best to do it before, during, or after the season?

CC: There’s never a bad time to be fitted but before the season makes the most sense. Frequency is really dependent on the player and what they’re looking to get out of their game but a rule of thumb is to check in on your gamer annually to be sure lofts/lies are still dialed in, to replace grips, etc.

GolfWRX: Do you ever recommend non-traditional putter styles?

CC: Yes! We have a couple armlock options, including the SIK putter that Bryson plays. We worked on an exclusive Bettinardi collaboration that yielded a great long-neck option. We even have a couple putters that stand up on their own so you can read the green with the putter lined up. We have a little bit of everything.

Mizuno unveils new T22 wedges

Published

on

Mizuno has introduced its new T22 wedges, which arrive in three new finishes and four grind options for varying techniques and conditions.

The new 2021 Mizuno T22 wedges are one-piece grain flow forged using HD boron and feature a microlayer of copper beneath the nickel chrome in a bid to deliver an extra split-second of control at impact.

2021 Mizuno T22 wedges: The details

The T22 wedges feature a slightly more compact, “modified teardrop” profile with an extensively bevelled top edge to make it appear thinner.

The spin weighted blade design, created by tapering the upper portion of the blade, is designed to create more consistent spin as well as a penetrating trajectory.

Speaking on the new T22 wedges, Chris Voshall of Mizuno Golf said

“I’d look at the T22 as a great balance between the ultra-classic looks of the older T7 and the performance traits of the T20. We’ve managed to bevel the top edge in a way to retain the performance of the T20’s tapered blade. But keep the more traditional look of the T7. Both models had a following for very different reasons.”

Mizuno’s HydroFlow Micro Grooves are designed to deliver excellent performance in wet weather as they’re laser etched to release moisture and reduce spin drop-off. At the same time, the Quad Cut milled and loft-specific grooves are cut into boron-infused steel in a bid to provide extra durability.

The T22 wedges are available in three finishes; Denim Copper, Satin Chrome (left-hand option chome finish only) and raw. The raw finish comes without the copper underlay and will rust over time to provide a look requested by many of the top Mizuno tour players.

Mizuno T22 wedges: Four grind options

S Grind – With minimal sole grind for fuller shots and lower lofts

D Grind – With moderate heel and toe relief, allowing gentle manipulation of the clubface

C Grind – With heavy heel and toe relief designed for more skilled players and firmer conditions

X Grind – With extreme heel and toe relief for experts

The T22 wedges will be available at retail from October 14th and are priced at $159.95 each.
