Blurred Lines: Mizuno launches JPX-900 Tour irons

Published

on

Mizuno, which has set the golden standard for players irons over the years, is blurring the lines between a blade iron and a forged cavity back with its new JPX-900 Tour irons. The new irons pass the eye-test for a blade, but they’re pumped up with performance features usually reserved for Mizuno’s bulkier JPX irons.

Like Mizuno’s MP iron models, which are designed for the most discerning and skilled golfers, the JPX-900 Tour irons are made from Mizuno’s Grain Flow forged 1025E Mild Carbon Steel to give golfers the familiar soft, solid feel for which Mizuno is known.

“We wanted to make the best Grain Flow Forged iron ever,” says David Llewellyn, Mizuno’s Director of R&D.

What’s different about the JPX-900 Tour irons is the more aggressive styling, which is part form, part function. The addition of Mizuno’s angular “Power Frame” to the cavity increases moment of inertia (MOI), which makes the irons more forgiving. Yet according to Llewellyn, the refined cavity-back irons should be an easy transition for its staff players, Chris Wood and Luke Donald, who currently use the company’s MP-5 blade irons.

Mizuno’s MP-64 irons, a forged cavity-back that many in the Mizuno community believe to be the best-feeling Mizuno iron in recent memory, was used as the benchmark for the acoustics of the JPX-900 Tour irons. By using the company’s HIT (Harmonic Impact Technology) system, which measures and quantifies sound frequencies, Mizuno was able to mimic the acoustics of the MP-64 irons while improving on their construction.

Specs

In terms of looks, the JPX-900 Tour irons are smaller than the MP-25 irons released in 2015, with a lower toe height and a “more modern design” than the MP-25 irons, Llewellyn says. Another note of distinction: the soles of the JPX-900 Tour irons which are thinnest ever used on a JPX model, and feature the same sole geometries Mizuno has been giving its MP irons for several generations. This design will create more versatility than ever from a JPX offering, something better players will surely appreciate.

JPX900_Tour_3Clubs+Shafts

The stock shaft for the JPX-900 Tour irons is True Temper’s Dynamic Gold AMT, which uses an ascending weight design to improve performance of each iron. In the X100 flex, for example, the 3-iron shaft weighs roughly 115 grams, while the pitching wedge shafts weighs about 130 grams. The lighter long-iron shafts help golfers hit higher-flying long-iron shots, making it easier to hit and hold greens, while the heavier short iron shafts provide added stability for greater precision.

JPX900_Tour+GolfPride

Mizuno’s JPX-900 Tour irons, available Sept. 16, will sell for $1,199.99 in either steel or graphite. There is no upcharge for custom shafts or grips.

    I use to play Mizuno blades for the longest time 14’s, 29’s and even the 33’s. Didn’t like the 32’s, but these look like they might be that perfect go between blade and cb. If they feel like my old time dizzy blades with a little extra punch Mizuno may have me back. But for now I’m sticking with my King Cobra pro mb/cb’s. Definitely can’t wait to demo. Love the minimal offset, one thing I din’t like about the 29’s in the scoring clubs was the huge amount of offset thus the Tiger combo of 29’s in long irons and 14’s in scoring clubs.

    I am using Mizuno TP9s with DG S400 shafts for the last four years (designed in 1986). I bought them from someone who had only used them four times from new (they were still in the original Mizuno box!). I find them well balanced and accurate and they look fantastic. The loft of the 7 iron is 37 degrees. Does anyone have any thoughts as to how they compare with MPs and JPXs should I want to change to a modern club?

    Does anyone else see the Ping s55 when you look at these irons? The toe portion of the cavity is identical as well as the general shape of the cavity. Overall design goal is exactly what the s55 achieved: smaller, players cavity back iron. Good news for all the fans of Ping’s S line who have being asking Ping to forge their clubs.

      Just the high toe weighting. Everything else is very different, including the unseen tech.

    To bad Mizuno doesn’t offer the Dynamic Gold Tour Issue shafts in custom. That’s my favorite iron shaft. These irons would be awesome paired with those shafts. Most of the club manufacturers carry that shaft but for some reason Mizuno does not.

    • L

      Aug 12, 2016 at 4:30 pm

      Not this again.
      There is no need for those shafts. Mizuno can build their clubs to precise spec with the standard ones. No need to spend the extra money for labels

      • Dane

        Aug 14, 2016 at 1:51 am

        It’s not just labels. The Tour Issue model has a tighter tolerance and are more consistent compared to the standard shafts. I can feel the difference between the two and others can agree with me. It’s the #1 shaft model on Tour. Titleist, TaylorMade, Callaway and Ping offer that shaft but not Mizuno. That’s unfortunate in my honest opinion.

        Also, Go to TrueTemper.com where they have a video explaining the differences between the two shafts. Your not paying more for a label, your paying more for a better, tighter tolerance and more consistent shaft.

        • Jim

          Aug 14, 2016 at 11:39 pm

          ….and everyone on tour was ALSO SST Pured….every shaft can be found to have a most stable plane to install in the head for optimum feel & performance.

          while it’s been illegal to manufacture a shaft specifically with a ‘spine’ to be inserted in a specific orientation, It’s not illegal to ‘find’ it in a shaft and reinstall it so it lies on a better axis…

          From what I remember originally they’re the same shaft, just cherry-picked. There wouldn’t be any difference in feel or performance between two shafts weighted the same, with the same playing characteristics. The only difference would be the label and the upcharge.

          An expert clubmaker could cherry pick the same exact Dynamic Gold shafts off the rack and there would be no difference, apart from the price. You’re only paying more for True Temper to sort the shafts correctly, which is arguably something they should do in the first place.

        • Scooter McGavin

          Aug 15, 2016 at 4:52 pm

          No, you can’t feel the difference.

            Aug 16, 2016 at 8:55 pm

            Some players won’t feel the difference between the standard shafts versus Tour Issue shafts but good players will. Plus the Tour Issue shafts look better with the Tour Issue shaft band.

            • Christopher

              Aug 17, 2016 at 4:10 pm

              They’re the same shaft, so they’re imagining a difference. The only difference is that each shaft will match your other shafts in your irons to a tighter margin, but you could cherry pick the standard Dynamic Gold shafts to achieve the same result. Imagine if you bought new pool balls for your 9-ball table, one or two balls are slightly heavier or lighter than the others, that would be your Dynamic Gold set, and the Tour Issue’s would all be same weight. They’re the same balls, they just have tighter quality control with the Tour Issues.

    “…should be an easy transition for its staff players.” Highly doubt LD would move from the MP-5 to a JPX iron. Going to be awhile before anything surpasses the MP-5. Looking forward to the JPX 900 driver though, which I think is the most interesting club of the new JPX line.

    I think they look very different for Mizuno in a good way. Really looks like the engineers spent their time on this one. A true leap in the generation of their products. I don’t care what they call them as long as they perform.

    They look like a streamlined version of the Titleist AP-2 irons.

    I have never owned a set of Mizuno irons but have always wanted to . Just never got around to it. I have some Wilson FG Tour V2s with some Nippon shafts that I just can’t kick out of the bag. These look really nice I never liked the looks of the 800 series and didn’t think the MPs were right for me. The MP-64s are beautiful and I was thinking about getting a used set for fun and to try them out. Maybe I’ll have to look into these. This is the first series of JPX irons that look good to me funny I always thought MPs were some of the best looking irons out there and JPX the worst . Hope to see some reviews soon. Maybe Mizuno will want some WRX testers.

    While the “no upcharge” is nice, if you prefer a more stock shaft – DG S300 – kind of have to feel you are getting hosed.

      Why would anyone take a chevy when the caddilac is the same price? They are not targeting the cheap end with these irons.

    • Jim

      Aug 14, 2016 at 11:30 pm

      Actually, it was a huge, smart move from Callaway…First year of Apex irons, they knew they were so good – and 1099 – $100 more than other big OEM’s ‘BEST’ they offered whichever shaft you needed for no upcharge. That helped make them a huge successs.
      When Rocketblades died a painful death after only 8 months and Speedblades (the next ‘greatest iron ever made’) came out with the same POS $9.00 shaft as Rocketblades for $899, getting into Apex (a FAR better head) w/KBS C-Tapers or Project X’s for 200 more wasn’t that big a stretch for shoppers.

      it’s a smart move for every OEM. Cripes – even Adams put CTapers in that funky black head a couple years ago, and they came to market for 699. It destroyed that dog Speedblade head…

      DG’s are reliable shafts – the standard we judge from – kinda like an IBM Mainframe – but if for no extra charge, you can
      definitely get a better feeling better performing stick.

      it always goes back to getting fit by an expert – with outdoor ball flight & proper launch monitor… Steel shaft tech has been blowin’ up big time in last 5 years. Take advantage of it!

    Looks cool. Smaller than the MP-25? Even better.

  15. Chuck

    Aug 11, 2016 at 12:10 pm

    1. So no tungsten in the soles or the toes? Do they accomplish most of what is going on with the tungsten inserts in other brands, with just the shape of the perimeter weighting? I’d be fine with that. My gripe with the tungsten-weighted Titleists was that the head was just a shade too compact for my own tastes.

    2. Are these the strongest lofts that Mizuno has ever offered?

    3. I would want a lot more information on the sole grinds. Does Mizuno offer anything custom in that regard? Can you order a blunted leading edge?

    4. So is this the prelude to a new MP model?

    • Brian

      Aug 11, 2016 at 12:55 pm

      1. Mizuno has never used tungsten inserts in their irons and these do not depart from that standard.
      2. These have the same loft specs as the MP-25, MP-15, and MP-5; so no, these aren’t lofted strong.
      3. You would likely have to order custom sole grinds from Mizuno’s Yoro arm and should expect to pay a premium to do so.
      4. No idea

        And, they are also still 1/4″ shorter than Titleist

        • kloyd0306

          Aug 12, 2016 at 8:57 pm

          Don’t you mean that Titleist are 1/4 inch longer than Mizuno?

          There is no industry standard for length. Who is to say that Titleist’s lengths are the correct length? Besides, stock lengths are only for stock clubs and if you are buying stock clubs from anyone, you may as well drive a car that does not have an adjustable seat, an adjustable steering wheel or adjustable mirrors.

          Mizuno measures length WITHOUT the grip. Titleist measures length WITH the grip. There is still a small difference but not a 1/4 inch when both are finished.

    Aug 11, 2016 at 11:34 am

    If they are in fact smaller than the MP25s then I’ll be salivating over these. May have to work up a combo set with MP25 4 and 5 irons

    They look nice, but as usual for Mizuno, they have way too muck offset in the short irons.

    Mizuno makes very nice clubs. If I were one of the current Nike staffers, I’d be talking to Mizuno. Even if that means a pay cut. Prob turn out to to be the same $ if they continue to wear Nike clothing.

Top 10 clubs of 2003—inspired by Adam Scott’s Titleist 680 irons

Published

on

As has been well documented, Adam Scott recently won the Genesis Invitational with a set of Titleist 680 blade irons, a design that was originally released in 2003. One of the great benefits of being one of the best players in the world is you don’t need to search eBay to find your preferred set of 17-year-old irons. Titleist has been stocking sets for Mr. Scott—even to the point of doing a limited production run in 2018 where they then released 400 sets for sale to the general public.

A lot of time has passed since 2003, and considering the classic nature of Scott’s Titleist 680, I figured now was a good time to look back at some other iconic clubs released around the same time.

Ping G2 driver

This was Ping’s first 460cc driver with a full shift into titanium head design. The previous Si3 models still utilized the TPU adjustable hosel, and this was considered a big step forward for the Phoenix-based OEM. The driver was a big hit both on tour and at retail—as was the rest of the G2 line that included irons.

TaylorMade RAC LT (first gen) irons

The RAC LTs helped position TaylorMade back among the leaders in the better players iron category. The entire RAC (Relative Amplitude Coefficient) line was built around creating great feeling products that also provided the right amount of forgiveness for the target player. It also included an over-sized iron too. The RAC LT went on to have a second-generation version, but the original LTs are worthy of “classic” status.

TaylorMade R580 XD driver

Honestly, how could we not mention the TaylorMade R580 XD driver? TM took some of the most popular drivers in golf, the R500 series and added extra distance (XD). OK, that might be an oversimplification of what the XD series offered, but with improved shape, increased ball speed outside of the sweet spot, and lower spin, it’s no wonder you can still find these drivers in the bags of golfers at courses and driving ranges everywhere.

Titleist 680MB irons

The great thing about blades is that beyond changing sole designs and shifting the center of gravity, the basic design for a one-piece forged head hasn’t changed that much. For Adam Scott, the 680s are the perfect blend of compact shape, higher CG, and sole profile.

Titleist 983K, E drivers

If you were a “Titleist player,” you had one of these drivers! As one of the last companies to move into the 460cc category, the 983s offered a classic pear shape in a smaller profile. It was so good and so popular, it was considered the benchmark for Titleist drivers for close to the next decade.

Cleveland Launcher 330 driver

It wasn’t that long ago that OEMs were just trying to push driver head size over 300cc, and Cleveland’s first big entry into the category was the Launcher Titanium 330 driver. It didn’t live a long life, but the Launcher 330 was the grandaddy to the Launcher 400, 460, and eventually, the Launcher COMP, which is another club on this list that many golfers will still have fond memories about.

Mizuno MP 33 irons

Although released in the fall of 2002, the Mizuno MP 33 still makes the list because of its staying power. Much like the Titleist 680, this curved muscle blade was a favorite to many tour players, including future world No. 1 Luke Donald. The MP 33 stayed in Mizuno’s lineup for more than four years and was still available for custom orders years after that. Unfortunately, if you are looking for a set now you are going to have to go the used route.

Callaway X-16 irons

The Steelhead X-16 was a big hit at retail for Callaway. It offered greater forgiveness than the previous X-14’s but had a more compact shape with a wider topline to inspire confidence. They featured Callaway’s “Notch” weighting system that moved more mass to the perimeter of the head for higher MOI and improved feel. There was a reduced offset pro series version of the iron, but the X-16 was the one more players gravitated towards. This is another game improvement club for that era that can still be found in a lot of golf bags.

Ben Hogan CFT irons

The Hogan CFTs were at the forefront of multi-material iron technology in 2003. CFT stood for Compression Forged Titanium and allowed engineers to push more mass to the perimeter of the head to boost MOI by using a thin titanium face insert. They had what would be considered stronger lofts at the time sounded really powerful thanks to the thin face insert. If you are looking for a value set of used irons, this is still a great place to start.

King Cobra SZ driver

In 2003, Rickie Fowler was only 15 years old and Cobra was still living under the Acushnet umbrella as Titleist’s game improvement little brother. The Cobra SZ (Sweet Zone, NOT 2020 Speed Zone) was offered in a couple of head sizes to appeal to different players. The thing I will always remember about the original King Cobra SZ is that it came in an offset version to help golfers who generally slice the ball—a design trait that we still see around today.

Today from the Forums: “The importance of wedge fitting”

Published

on

Today from the Forums we delve into a subject dedicated to wedge fitting. Liquid_A_45 wants to know if wedge fitting is as essential for golfers as iron fitting, and our members weigh into the discussion saying why they feel it is just as imperative.

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.

  • Z1ggy16: “Super important if you’re a serious golfer. Even better if you can get fit outdoors on real grass and even go into a bunker.”
  • ThunderBuzzworth: “The biggest part of wedge fitting is yardage gapping and sole grinds. If you have a grind that doesn’t interact with the turf in your favor, it can be nightmarish around the greens. When hitting them try a variety of short game shots with different face angles etc. with the different grinds to see which one works best for what you need.”
  • Hawkeye77: “Wedge fitting I had was extremely beneficial when I got my SM6s a few years ago. Mostly for working with the different grinds and how they interacted with my swing and on different shots and having an eye on my swing to help with the process and evaluate the results. My ideas of what grinds were right for me based on researching on Titleist, etc. just were not correct in 2/3 of the wedges I ended up with as far as the grinds were concerned. Good to have an experienced fitter available to answer questions, control variables, etc.”
  • cgasucks: “The better you get at this game, the more important wedges are.”
