Ask Mitsubishi Answered

Published

on

Some time ago I started a thread in the forums that posed this: “If you could ask the engineers behind Mitsubishi shafts a technical question (or questions) about their product what would you ask?” The board answered and following is the resulting dialog that I received back from Mitsubishi. All information is exactly as it was received from the company:

 

1. Exactly what criteria = high launch low spin

ANSWER:  There are no exact criteria that “equal” high launch and low spin for all players.  In fact, the conditions that promote optimal launch and spin vary greatly from player-to-player depending on a player’s swing speed, equipment, and ability. For example a PGA Tour player with a ball speed of 170MPH may benefit greatly from a launch of 13 degrees and spin rates of 2500 RPMs. However, an average player with ball speeds of 130mph may need higher launch angles and spin rates to maximize performance and distance.  This is why we always recommend visiting an authorized club fitter to find out what combination is best for your game.

2. Do you acknowledge the practice to spine align or pure any of your shafts? Do you condone it? If not, why not?

ANSWER: There are a variety of techniques and procedures that promote alignment optimization and if using those techniques has an impact on your club’s performance you should consider the application of such techniques when fitting and building your clubs.

3. Why were the heavier weights (93 and 103) not carried over into the red/whiteboard lines?

ANSWER:  We continue to experiment with heavy-weight product primarily for Tour player use and product testing.  To date, the consumer demand is such that we limit the amount of heavy-weight product produced for retail use however we are constantly looking to add to our mix of SKU’s offered to our dealer network.


4. Does Mitsubishi have any plans to release a Low Torque (2.0-2.9) shaft in the near future?

ANSWER:  In fact Mitsubishi Rayon has several product lines that offer lower torque by your definition (including Blue Board Diamana, White Board Diamana, and Diamana Kai’li)  and we will continue to develop and experiment with low torque designs for future product lines.

5. What is the next step in shaft development? What should we be looking for in the near future from Mitsubishi? How much more do they think they can push the "technology envelope" with regards to spin reduction, launch angle management and dispersion?

ANSWER: This is an interesting question that requires a two-part answer.  In the “short-term” you will see Mitsubishi Rayon working to maximize the benefits of two recently released technologies developed by our team of engineers; MDT and MDI:

Modulus Differential Technology (MDT) is a process by which fibers with different responsiveness characteristics can be joined and blended in precise ways and has made its debut in the current Fubuki™ profile.  By applying MDT technology in pinpoint locations along the shaft, we can create unparalleled consistency in spin reduction and dynamic launch angles in a range of shaft profiles.  Look for future iterations of this design technique in the coming months.

Multi-Dimensional Interlay (MDI) on the other hand is a process by which we strategically position multiple layers of proprietary ultra-thin material at multiple angles of orientation throughout the entire length of the shaft.  This design technique delivers unparalleled consistency and control by minimizing torsional deformation in both the butt-section during unloading and in the tip-section through impact and has first been used in the most recent profile of our Flagship brand Diamana.

In the “long-term” what is “next” for Mitsubishi Rayon depends a great deal on what is next from club head designs.  We are constantly working with our partners to maximize the performance of next generation club head designs as well as to meet the needs of the best tour players in the world.

6. Is there any chance of the Fubuki being produced in higher weights for retail?

ANSWER: We are currently experimenting with a variety of weight and the impact of our MDT technology on those profiles.  Stay turned to GolfWRX for updates!

WRX Spotted: New TaylorMade P790 UDI

Published

on

It’s Open Championship week and that means course conditions are the talk of the town. Firm, fast, and windy conditions are expected on the links of Portrush, so we will be seeing a lot of players using driving irons that they might not otherwise play with week to week on the PGA Tour.

Not only are driving irons a hot item for players, but for OEMs launching new and prototype versions including TaylorMade, which has a new P790 UDI in some bags including Mr. Tiger Woods (credit to Rob Brooks on Instagram for the spot).

Like with many clubs just being seeded to tour, we don’t have official comment from the team at TaylorMade…but, like many times before, we have a couple of ideas based off the cosmetics of what might be in store if and when this thing comes to retail.

Some history: It’s been a while since TaylorMade introduced a new UDI (Ultimate Driving Iron) to its lineup.  There was the GAPR Low, which was very UDI “like” but the UDI as a whole never had an adjustable hosel. (There were Tour Issue versions of the GAPR Lo that had a fixed hosel and no adjustability)

The original (2017) P790 UDI

The “just-spotted 2020 (?)” version

The most recent UDI was the original P-790, but this new version has some distinct differences

  • Thinner sole. Based off the pictures, this new P-790 UDI has a thinner sole with more camber to help improve turf interaction. More camber and well-utilized bounce make any club more playable in varying conditions.
  • Shorter blade length. There is no such thing as computer screen calipers but from what we can tell when comparing side by side the new version is shorter. A shorter blade length means a CG closer to the hosel and more workability.
  • Higher toe. Just like the shorter blade length, a higher toe is often more appealing to more players (better players are generally the target for these types of clubs) and what that also “potentially” does is raise the CG. A higher CG will produce lower launching shots BUT with more spin (workability). To counter act the potential extra spin loft adjustments can be made pretty easily, since loft is one of the biggest factors in creating spin.

The one thing that is harder to compared is whats going on inside of this UDI (obviously). There is a screw in the toe, so it can be assumed that there is some sort of foam or material that helps support the face and improve the acoustics of this face thin-faced iron.

Just like we wait for the first group off early Thursday morning at Portrush, we’re just going to have to wait to see what’s really going on this new UDI too.

Forum Thread of the Day: “Tiger Woods with a new Scotty Cameron at The Open”

Published

on

Today’s Forum Thread of the Day comes from No Gimmes who was quick to spot Tiger Woods preparing for this week’s Open Championship with a new Scotty putter. Woods has also been seen warming up for this week’s event at Royal Portrush with his old faithful on the greens, but our members have been discussing the thinking behind the 15-time-major champion’s potential change, as well as the putter itself.

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.

  • TheMoneyShot: “I’m really surprised he is making the switch. Let’s see if it’s in the bag come Thursday.”
  • Hedgehog: “That topline and the alignment aid and all the smooth lines, gorgeous!”
  • MuniPukeLife: “Makes sense as his trusty NP2 is super light by today’s putter standards.”

Mizuno T20 wedges: Let’s get spinning

Published

on

Spin.

We’re always trying to reduce it with our driver and increase it with our wedges for maximum control, but with the rules of golf being so strict, how do actually achieve a performance gain? Simple engineering…

This is the Mizuno T20 wedge.

It’s been a few years since we have seen a T (teardrop) wedge from our friends at Mizuno, and there is good reason.

Let’ get into a quick history lesson: before the JPX900 series was introduced, Mizuno had quietly been realigning the product cycles of the MP and JPX lines. You might remember back a few years ago now before the MP18s hit the scene that there was a bit of a lull in the MP line—so much, in fact, there was even a thread here on GolfWRX asking “Is Mizuno not making MP irons anymore?”

It was a naturally curious question to a company that always had very standardized release cycles, but it was a long-term play that has paid off tremendously. We now get “T” wedges with MP irons (MP20s to be exact), and we should (from everything I know) continue to see “S” Silhouette (more rounded profile) wedges with future JPX lines.

Before we get to what’s new, how about we first talk about what will be staying the same

  • Grain Flow Forged HD – like all new Mizuno irons, the T20s are made using the same forging process to increase the density of the material in the clubhead for an improved solid feel.
  • Boron – this little element when added to the 1025e mild carbon steel used in the wedges (we’re talking trace amounts equating to 3ppm – parts per million) increases the strength of the material by 30 percent—how crazy is that for chemistry? This improves groove life and has ZERO effect on club feel.
  • Variable Width & Depth Quad Cut Grooves – Like previous T and S wedges, the T20s will have quad cut grooves that will vary in shape based on the loft of the club. Lower lofted wedges are more narrow and deeper, while higher lofted wedges are wider and more shallow since impact happens at lower speeds this increases spin consistency.
  • Same beautiful Teardrop profile from address

So what’s new?

Flow. Just like the MP20s, engineers are bringing more a more extreme CG (center of gravity) shifting philosophy, or as Mizuno explains it, increased vertical moment of inertia to the wedges. As much as you (well maybe not “you,” depending on who you are) might think “a wedge is just a wedge” and loft is the only deciding factor for spin, you couldn’t be further from the truth. By relocating the CG throughout the set and changing the sweet spot height, engineers can further alter the launch and spin precisely for each loft.

It’s about gear effect—the higher you hit above the CG the less spin the ball with have, and the closer to or lower you make impact compared to the CG the more spin you will create. Either way these are wedges, so a 50 degree, for example, is still going to spin, but it is now more controllable (think less likely to ballon or get too high on full shots). On the other side of the equation, a 60-degree wedge will allow for even MORE trajectory and spin control for the low flying quick checkers with zip.

Now about that spin.

By the Rules of Golf, you can’t make grooves sharper, you can’t increase their volume, and you can only have so much surface roughness (sorry but that old Spin Doctor wedge is HIGHLY NON-conforming). So what do you do? You change the way you think about that surface roughness…

Hydroflow Micro Grooves

Instead of traditional laser etching parallel to the grooves, Mizuno engineers took a concept from the high-performance tire world and went perpendicular to the grooves and parallel to the direction the ball moves up the face to channel moisture away. This directional tread has proven to increase spin on shots especially in conditions with moisture up to 1,200 RPM (on a 60-yard shot), that’s a very tangible number. It’s not just about spin either: the more the friction that can be created also means more control on launch angle and less of a “floating” ball flight. That’s how those low zippers keep zippin’!

Don’t think for a second that Mizuno just changed the etching and was done with it. The process went through multiple iterations to figure out how they could improve its life (beyond the boron) and the solution was to etch before the chroming process to elongate the lifespan. The other groovy take for the T20s is the actual reconfiguration of the grooves. To get the bottom groove closer to the leading edge without having it disorient the overall look of the club and making it appear that the heel or toe is thinner on one side. The lowest groove has been shortened and centered.

All of these refinements; CG, micro-grooves, and reconfigured scoring lines add up to one thing: more control and improved shotmaking with your wedges.

Finishes, specs, and grinds

The wishes of many have been answered when it comes to the T20s, there will be a RAW finish (happy dance time) along with traditional chrome and the signature blue ion. Leftys will only be able to get chrome, but all the same options will be available as far as lofts and grinds.

Coming in lofts from 46-60 degrees, the grind options progress depending on the loft and bounce. Going from full-soled in the lower lofts to more aggressive back edge, and heel-toe relief in the 60 degree. These sole shapes came directly from Mizuno’s craftsman that worked with players and prototypes to determine exactly how the bounce and sole shapes should work in harmony.

All of this has come together to create Mizuno’s finest wedge to date.
