If Tour pros could play any set of irons with no contract restrictions or obligations, what would they use?

In the world of professional golf, which is heavily influenced by profit, we’d usually never get that answer. But this year, due to a number of factors including Nike’s exit from the golf equipment industry, numerous players are left without commitments to a particular brand. That means more golfers than ever are playing irons of their choice.

Based on our photos from the Arnold Palmer Invitational, and recent weeks, it appears many of those players without iron contracts are deciding to play Mizuno irons.

In recent years, there was usually between 1-3 sets of Mizuno irons in the bag at most PGA Tour events. At this week’s Arnold Palmer Invitational, however, there are 8 players using a set of Mizuno irons. Even more interesting is that 75 percent of them are using or testing the same Mizuno iron model: the JPX-900 Tour

  • Mizuno Iron Model: JPX-900 Tour (built this week), most recently MP-4
  • Full WITB: Vijay Singh WITB 2017

We spotted Vijay Singh with Mizuno JPX-900 Tour irons in his bag on Monday. On Wednesday, however, he was bagging Mizuno MP-4 irons. It will be interesting to see what he decides to use going forward, but it’s likely it will be stamped with the Mizuno brand name.

  1. I have mp-14s and 54s funnest even for a 10 hc. Can’t beat the feel and the shots are so satisfying. I have played PRGR, Data 601s, and they are awesome but the there is nothing like an mp-54. Also game Bridgestone j38 double pocket cavities, but they were not as consistent as the 54s. I can’t game the 14s anymore, but they sure were a great iron. I still take them out at times but I cannot weiled them like I used to. I still get a few awesome shots with them and I still say wow.

  2. Hard time deciding weather ship my MP-29’s down to the desert, or the 712MB’s. Need to have something down there to fly light and exit the airport quickly, too many Id*ots sucking up oxygen when I travel down to the valley.

  3. I’m sticking with my homemade Maltby TE’s which replaced my MP52’s. Just nothing else on the market like them for size, shape, forgiveness, feel, etc. although Titleist CB would be a close second.

  4. Does this surprise anyone? Mizuno makes the best feeling irons and TM makes the best performing woods. That is why if you let a pro choose without endorsement you see Mizzy irons and TM woods in the bag. The funny thing though is that performance wise irons haven’t really changed in years. I played a round recently with my old ’95 King Cobra Oversized irons while my MP-64s were in transit and they may have been 1-2 yards shorter (Same DG S300 shafts in both) and thats it. The feel was the only difference.

  5. My current set is JPX900 Forged with Project X LZ. Best irons I’ve had out of TMAG RBZ, MP-29, MP-59. I’m a 12HI and play 6-8 times a month. Great irons, great shafts for me.

  6. Been in the bag since a set of Tommy Nakajima’s gifted by a client. 8 or so sets later and I’ve never considered looking over the fence. I wonder if Mizuno is offering performance pay for tour players. Keeps things simple and everybody on their toes.

  7. Used to play MP14’s and then MP37’s. Sure wish I could play them again. 72 and RA makes you play graphite and something more forgiving. Don’t like any of the new so called forgiving irons, still play the 2008 TM Tour Burners. Maybe I’ll try the JPX900’s.

  8. I have played all types of irons and no other surpasses Mizuno. Have 4 different sets in my golf room. Have a set of Callaway CF16 and they are long and go high and that is good for me. Also tried the Titleist MB-T and they fly high and feel good. I was using the Nippon 880 AMC shaft. I do like the Nippon family of shafts. Have tried almost every shaft I could get my hands on. For a heaver shaft the the modus tour 130 has a great feel. Any questions or comments just email me.

    • With all respect Daryll, why can’t you settle on what works best for you or is it a little OCD stuff with golf equipment? I can get that way about my cars so I understand.

  9. Not surprised really. Mizzy was #1 on the PGA tour for 12 years in a row. Some guy came along and wanted to get paid; everyone else wanted to get paid also. Their reign was over!! Probably the safest choice for anyone looking for a great forged iron. No gimmicks, and their heads seem to keep the same size, shape, and weight. I’ll take them any day over the bigger OEM’s in the industry.

  10. Been a forged Mizzy guy for a very long time, so no surprises in your report. But I have Miura cavity backs as my scoring irons (CB201s, 7-9), and, when you hit ‘em right, there’s something about the sound of that Miura click that says, “You don’t have to look up. It went where you wanted it to.”

  11. Just got a set of of the JPX 900 Hot Metals. Price wasn’t an issue and hit all three and with the hot metals the ball was just flying off the face. The forged felt a bit clunky and the tour was nice but maybe a little too much for my 12 handicap. Paired them with the Modus 105s (LOVE THEM!) and some MCC plus 4’s and i’m itching for the courses to open

  12. I have built multiple sets this year with the 900 Forged long irons and the Tour short irons. A little different feel with the Forged (Boron) version but they are much more forgiving for the average player in the longer clubs. See your custom guy and try this route rather than the Tour irons all the way.

  13. I play two year old forged 850’s and the 4 some I play with have all hit them and ask me to leave them to them when I pass. We play two sums for lunch once a week and my partner plays out of my bag because no matter what shot he hits he just flat love’s the feel.

  14. As a longtime Mizuno player I still bag MP64. I DESPERATELY wanted to play the new JPX900 Tours but they feel terrible – and I’ve heard that being the consensus. They aren’t even remotely like a Mizuno and they really don’t even feel forged. Vijay had them in the bag for a week and claimed he hated the feel so he switched to the MP4’s for the Arnold Palmer. I truly think the 900 Tours are gorgeous. But I tried 3 different shafts and they still just feel hard. Really upset about this. Not trolling because I WANT them. I keep going back and re-testing them because they looks so good :)

    • My buddy games the 900 tours and I’ve hit a few shots with them, they felt pretty solid and soft. Not trolling you or anything but where did you see that Vijay said that? Just want to read the article, if there is one.

    • I didn’t have this experience either, I actually thought they felt really nice. No, not quite like an MP4/MP5… In my experience, though, choice of ball matters a lot on the feel of most modern irons. I find the feel (and sound) of many modern balls to be very different, and in some cases – I’ve noticed with putters, for example – the best feel is a combination of club and ball. In other words, the best feeling ball depends on which club and vice versa.

      Also, is your experience with the JPX900 in using the demo club? If so, those screwed together demo irons IMO don’t feel as good as they do once epoxied. And obviously choice of shaft is huge.

  15. Not surprised..when I started golf in 2000, Mizuno has stated at the time that they’re the #1 irons on the tour…then one day, TM started to give tee up money to non-staff players to use their irons and drivers and has been that way for a long time. I hope Mizuno goes back to being the #1 irons on tour again.

  16. Loved the mp-29s back in the 90s and thought they were best out there. Have not tried Mizuno irons for a while. My quirk with them is I wish they would have stuck with the old “M” as their logo. Don’t know what the new one means at all. Looked much more classy with old logo that’s just me

    • “For many years, Mizuno had used a distinctive large “M” logo. This logo was integrated into the stripes on the sidewall of many of its baseball and running shoes, but due to a trademark issue and the feeling that the Mizuno “M” was deemed too similar to the Adidas three stripes, a more modern Mizuno logo was needed that would also signify the company’s expansive views.”

      “The Runbird—a beautiful, free-flowing, graphic emblem of the Mizuno brand—is more than just a logo, adorning shoes, clothes and gear. Instead, the Runbird symbolizes Mizuno’s roots in the Japanese concept of its universal approach to sports with unlimited space and energy.”

      There ya go.

  17. I played mizuno mp-29s back in the 90s and thought they were awesome clubs. I’m sure today’s models are nice too. Just wish they wouldn’t have switched the “M” logo to that strange looking thing they use now I know it’s just a quirk but I wish they went back to old logo

    • I just got a set of Leftie MP900 Hot Metal Irons and they are amazing. I have 5 thru lob with an M2 Driver, no contract,lol. As club maker and repairman Mizuno has always been the top quality in my opinion and when you are working on clubs you find out what is quality and what is not. I have Callaways, TMs, and other “top of the lines”,,, no comparison.

    • I feel your pain, lefties. My mom makes up one of your sinistro numbers.

      In an era when golf companies are wailing and gnashing their teeth about “decline” in right handed golfers, you can surely understand how the capitalist solution is to disenfranchise the 5%. Corporate America tends to dump products that “only” sell at a 10% level, etc.

      There is no easy solution. You could find a way to surgically implant the long-lost heart (or conscience) into capitalism. You could try to find a way to make left-handed clubs more profitable. This might involve drafting masses of lefties into golf, or long-term breeding of the recessive gene (which is 50/50 right-left). Or find someone to pull a Ned Flanders and create a Left Hand Golf club OEM and Superstore. My first suggestion is preferred since it might improve more things too.
