Mizuno brings the MP family closer together with its new MP-18 irons

Published

on

With its MP-18 iron family, Mizuno has narrowed the differences between its four new iron models to make mixing sets not only easier, but completely seamless.

Check out our WITB Page, and you’ll notice that most PGA Tour players are using combination iron sets. That means they’re playing muscleback short irons and cavity-back longer irons with thicker toplines and more forgiveness. This combo-set trend makes perfect sense; it allows golfers to use an iron set that gives them maximum control in their short irons where they want maximum control, and more forgiveness and distance in their long irons where they want more distance and forgiveness. Duh!

The problem is that most iron sets attempt to cater to the needs of muscleback players with their muscleback irons, cavity-back players with their cavity-back irons, and game-improvement players with their game-improvement irons. By segmenting iron families, it leaves gaps in looks, feel, playability, and distance for golfers who want to make their own combination set.

Mizuno has gone to great lengths to address that problem with its MP-18 iron family, which is intended to be mixed and matched. The MP-18 family includes four irons types:

  • MP-18 (Muscleback)
  • MP-18 SC (Split Cavity)
  • MP-18 MMC (Multi-Material Compound)
  • MP-18 MMC Fli-Hi

While the SC, MMC, and MMC Fli-Hi irons are larger than the MP-18 muscleback irons, they maintain the same sole, head profile, and topline ratios in their shaping. That means they look almost identical at address; they’re just slightly larger. Their lofts and pricing are also essentially identical. Only a trained eye will be able to tell any difference at all.

In terms of materials, Mizuno went back to its roots with the MP-18. The irons are forged from 1025E Pure Select Mild Carbon, a switch from the 1025 Boron the company was using in some of its MP irons in recent years. Boron was used because it is stronger than Mizuno’s 1025E carbon steel, allowing engineers to thin out structures within the irons for added distance and forgiveness. “That’s just not MP,” as one Mizuno representative put it.

With this launch, Mizuno strived to give the MP-18 irons the look and feel of irons that “could have been made 100 years ago,” the company says. They’re for players who want the best-feeling, best-looking irons they can play, with simple color schemes and classic shapes, while still getting maximum performance. There’s still a place for cutting-edge designs and materials in Mizuno players irons — just ask Brooks Koepka, who used the JPX-900 Tour irons forged from Boron to win the 2017 U.S. Open — but it’s not in the MP-18 line.

To get the artistic shaping the company desired in the MP-18 line, Mizuno brought its computer-designed club heads to Japan where its expert craftsmen refined the shapes. The club-grinding experts worked to blend the transition of the hosels into the club faces in a way that reduced the look of offset. They also dialed in toe and heel shapes while adding camber to the sole. These prototype models were used as the starting point for each of the MP-18 irons to ensure consistency through the lineup.

Despite their throwback looks, the company relied on new school technologies to refine the sound and feel of the irons. Mizuno’s stated goal with the irons was to extend impact frequencies so they not only feel softer, but so that golfers get more feedback on the club. To that end, the irons were forged with a new “Grain-Flow Forged HD” process. The company’s H.I.T. (Harmonic Impact Technology) was also used to dial in acoustics for enhanced feedback.

Below, we break down each of the individual offerings in the MP-18 family. The irons will sell for $149.99 each and will be available September 15.

Mizuno MP-18

In relation to previous Mizuno MP muscleback irons, the MP-18 irons are significantly smaller than the MP-5 irons and slightly smaller than one of Mizuno’s smallest modern muscleback irons, the MP-4. Their toplines appear thinner than they measure due to a camber that makes them look slimmer in the address position. In comparing topline thicknesses, the MP-18’s are thinner than the MP-5, but they’re a bit thicker than the MP-4.

The MP-18 scoring irons (9 and PW) are smaller in size than previous models. All of the irons in the set also have lower heel heights. “That’s what this player wants,” a Mizuno representative said.

The MP-18 irons will come stock with True Temper Dynamic Gold S300 shafts and Golf Pride MCC White/Black grips. They are right-handed only offerings.

Mizuno MP-18 SC (Split Cavity)

The MP-18 Split Cavity irons feature what Mizuno calls a half-cavity design. Mass has been taken of the upper portion of the irons, focusing CG (center of gravity) lower in the club head for an easier launch and more forgiveness.

The MP-18 SC irons are only fractionally longer from heel-to-toe than the MP-18 muscleback irons. They’re also 0.5 millimeters taller and have soles that are 1.5 millimeters wider. With identical specs (aside from swing weight in the longer irons) and offset, these irons are designed to blend seamlessly into a combination set with the MP-18 muscleback irons regardless of where golfers decide to split their set.

The MP-18 SC irons come stock with KBS Tour shafts and are available for left- and right-handed golfers.

Mizuno MP-18 MMC (Multi-Material Construction)

The MP-18 MMC irons are Grain Flow Forged from 1025E, but they use a multi-material construction to move weight to the center of the club heads to enhance moment of inertia (MOI), a measure of forgiveness. The more centered CG is achieved by adding 20 grams of tungsten, a material more dense than steel, in the toe section of the irons. An 8-gram titanium insert, which is lighter than steel, was also placed behind the club face and toward the heel section of the club.

The titanium insert is used in each of the MMC iron designs. Tungsten was not used in the 8, 9, and PW club heads, however, as it was not needed to center CG due in those clubs.

MizunoMMCconstruction

The MP-18 MMC are designed with 0.8 millimeters less offset more than the MP-18 and SC irons, but they also have 2 degrees less loft per head. According to Mizuno, however, each degree of loft that is added when bending an iron weaker adds 0.4 millimeters of offset. That means if a golfer matches the lofts of the MP-18 MMC irons to the MP-18 or MP-18 SC irons, offset will be essentially identical.

The MP-18 MMC irons will come stock with a Nippon Modus 120 shaft, and they’re a right-handed only offering.

Mizuno MP-18 MMC Fli-Hi

Offered in long-irons only (2-6 iron), the Mizuno MMC Fli-HI irons have an X-30 steel body material with club faces made from Maraging 1770HT steel, a high-strength material that can be made thinner to help create faster ball speeds.

MizunoTngsten

Mizuno made the toplines of its new Fli-Hi significantly thinner than its predecessor, the MP-H5 iron. The toplines are also cambered to look thinner than they measure, creating a look that will suit the eye of better players, according to Mizuno. Like the MP-MMC irons, the MMC Fli-Hi irons also have 20 grams of tungsten in their toes. The insert is forged into the inside of the cavity, however, and it sits behind the face. According to Mizuno, this design helps golfers hit higher shots with the irons and increases forgiveness.

The MP-18 MMC Fli-Hi irons will come stock with KBS C-Taper shafts, and are a right-handed only offering.

    No combo set if you’re left handed, which is a big fail. I wanted the sc18’s, but it feels like mizuno doesn’t want my money. No fli hi is a deal breaker for me. Add to that the blue wedges and I think they should just stop making left handed clubs altogether. Any self respecting lefty wouldn’t play Mizuno.

      What do most people need with a combo set. Is it skill or ego that they think it will make them a player with them in the Bag. I am a leftie and play with the Hot Metals in Leftie that more people need, they are strong, hit high and feel soft. And the Graphite shaft is a good one.

      So Leftie, take a good look at then, them, then are grrrrrrrrreat.

    Think you meant to say tungsten was not used in 8-paw heads of MMC. You wrote titanium.

    I’m surprised by the fat soles on the 18’s. How’s that “classic Mizuno”? I’ll wait to see them in hand but that really pops the bubble for me…

    When you say the Fli-Hi iron’s are only offered in the long irons and then you put in parentheses 6-PW. I think you meant to write 2-6.

    Surely these MP18’s can’t be any good they are not over $3000 for 8 irons!!

New XXIO Prime woods, hybrids, and irons aim for lightweight power

Published

on

xxio-prime-feat

XXIO’s latest club offerings, XXIO Prime, looks to offer easy distance and easy accuracy for the moderate swing speed golfer, according to the company.

XXIO Prime woods

xxio-prime

XXIO Prime Woods feature a new re-designed hosel structure, and reduced stiffness at the tip of the driver shaft, which is designed to help moderate swing speed golfers to close the clubface through impact.

Forged from Super-TIX PLUS Titanium, the new cup face includes a sweet spot that is noticeably larger than previous designs, which aims to increase distance performance significantly. The Super-TIX PLUS Titanium Cup Face is thinner, lighter and stronger than previous additions, creating a maximum COR across the face, which aims to increase ball speed and distance.

According to Chuck Thiry, Vice President of XXIO USA

“The speed increases, higher launch angles, and draw bias of the new Prime will show immediate results from swing one. It’s legit lightweight power for the players that absolutely need it the most.”

Featured in the XXIO prime woods is the SP-1000 shaft, with TORAYCA T1100G carbon fiber and NANOALLOY resin, which creates a strong but lightweight club. Along with the lightness in the shaft, XXIO has made weight savings in the grip and club head, which aims to produce woods that are both fast and easy to swing.

The XXIO Prime woods feature an expanded toe and narrowed heel, a tungsten-nickel inner weight that is low and deep, a lighter hosel repositioned closer to the center of the face, and reduced stiffness at the tip of the shaft, all with the aim of offering golfers with maximum forgiveness from their woods.

The XXIO Prime woods will be available from March 1 and will cost $579,99.

XXIO Prime hybrids and irons

The new XXIO Prime hybrids feature an expanded COR and a lower center of gravity, which is designed to increase distance and ball speed while delivering a straighter ball flight.

The hybrids from XXIO contain a Forged Maraging Steel Cup Face which includes a large sweet spot which aims to increase distance performance.

Just as with the woods, the XXIO irons also feature the Super-TIX PLUS Titanium Cup Face, though along with this, they also contain a CNC milled speed groove, which significantly increases the COR, creating a larger sweet spot, designed to provide greater distance, ball speed and accuracy.

Both the hybrids and irons include the SP-1000 Shaft, with TORAYCA T1100G carbon fiber and NANOALLOY resin. The hybrids and irons also feature weight savings in the grip and club head, with the aim of increasing swing speed.

With an expanded toe and narrowed heel, plus a crown step that moves weight low and deep, XXIO claim that this is their most forgiving suite of Prime hybrids. While with two high-density tungsten nickel sole weights and an overall profile that is 3mm shorter than the previous model, the company also claims to have created their most forgiving irons yet.

Speaking on the new XXIO Prime series, Chuck Thiry stated

“XXIO Prime is, quite frankly, the most unique and beneficial product ever available to moderate swing speed players. Period. People might think that is marketing hype, but they simply haven’t hit Prime yet.”

Both the XXIO Prime hybrids and irons will hit retail stores on March 1. The Prime hybrids will cost $379.99, while a single graphite iron will be available for $259.99.

SPOTTED: 2019 Mitsubishi shafts

Published

on

2019-mitsubishi-diamana-shafts

The Diamana shaft line from Mitsubishi Chemical is probably one of the most iconic in the sport. Released in 2005, Blueboard, Whiteboard, and Redboard, were the first generation of shafts.

Photos of the full fourth generation Diamana lineup, offering new materials and technology, along with new names, have surfaced in the GolfWRX forums. Like previous generations, each color shaft offers different ball flight and spin characteristics.

“RF” is the highest launching and spinning in the Diamana line, offering high launch and mid spin, while the “BF” is the mid-launch and mid/low-spin model. Finally, the “DF” is mid/low-launching and the lowest-spinning shaft in the lineup.

All of the fourth generation Diamana shafts use updated technologies and materials that you would expect from a premium lineup. DIALEAD pitch fiber is helps reduce shaft deformation, while still producing exceptional energy transfer.

Each shaft contains MR70 carbon fiber that is 20 percent stronger than conventional materials and Boron fiber for its compression strength and shaft reinforcement. ION plating has been done before in the Diamana line, in vacuum chambers — silver alloy ions are bonded to the shaft to give it a chrome-like finish that can’t be replicated by paint.

SPOTTED: 2019 Aldila shafts

Published

on

aldila-2019-shafts

With the beginning of the PGA Tour’s West Coast swing on now, we are really starting to see more 2019 gear work it way onto tour trucks, and onto the range for player testing…and into our forums (in picture format, at least).

Some of the most recently spotted pieces are the 2019 Aldila ATX shafts, including what appears to be an 85g hybrid shaft and a 120g iron shaft.

aldila-2019-shafts

We can only speculate that the hybrid is a low launch shaft — based on the PGA  Tour testing being done, but this could be a shaft more suited for the growing popularity of the driving iron category vs. wood-like hybrids in the previous couple of seasons.

The 120g iron shaft has a lot of people talking, since Aldila has leaked some information in our picture thread

“It utilizes a custom prepreg made at our facility in Poway that features a “Metal Mesh” material that is combined with Carbon Fiber to help add stability and weight in the irons.”

aldila-metal-mesh

By using this custom material, Aldila could be solving the common problem that a lot of people have with graphite, and that is the club total weight — although in this case 120g is similar to a lot of steel iron shafts already being used on Tour. As prototyping goes, this material could be put to use in lighter versions of the shaft and have a greater benefit in the sub-100g category — if they plan on going that route.

For the drivers, if previous versions and colorways are any indication, it looks like we will have some new technology packed into popular bend profiles like the NV (Green) and the VS (Blue).  As some members on the forums have already discussed, these shafts will be utilizing graphene (an extremely strong carbon material) for additional stability. 

We also have new Rogue 130 MSI models following along similar lines with both a black and silver.

Here’s some additional information from Aldila

“Building off of the success of the ROGUE® Limited Edition – which featured 125 M.S.I. Graphitic Carbon Fiber, we have taken ROGUE® to performance to another level by incorporating even stronger 130 M.S.I. Graphitic Carbon Fiber. The ROGUE® Silver 130 M.S.I. is a low-launch, low-spin shaft with a low torque tip-section fortified with 130 M.S.I. Graphitic Carbon Fiber, a higher balance point, and a premium ion plated finish.”
