I did this experiment because I am currently using blades after using game-improvement irons for a long time. And after a few rounds with the blades, I have found no real drop in performance.

Moment of inertia (MOI), a measure of an iron’s forgiveness, is as a selling tool for new irons, but I am not sure how much real improvement it is offering the golf community. My video goes a long way to show that maybe the way we’re thinking about fitting irons to our game is quite wrong. 

Both the irons I tested in the video had stiff shafts. The Mizuno MP-5 (blades irons) had True Temper’s Dynamic Gold S300, while the JPX-EZ (game-improvement irons) had True Temper’s XP 95 S300 shafts. Both irons were tested with stock lofts and lengths.

    I’m a 10 handicap and play a set of blades and I often hear comments like “wow blades, why make the game harder?” or “you must be really good if you are playing these clubs” (which i’m not really good, I’m just average). Truth of the matter is, a crappy shot is a crappy shot. A GI club isn’t magically going to turn a chunk into a pure shot pin high. It IS true that your off center shots will most likely fly further with a GI club, but not by a significant amount. And for me, blades offer the “feel” when you hit that pure shot to know you hit it pure. Feedback in a club is an important part of improving your game. I’m not advocating that everyone should play blades, it’s a personal preference. But I think we need to realize that blades are not just for scratch golfers.

    I would like to see a high handicapper do this experiment. Someone in the 20s range go through this with the data so we can see side by side if GI irons are better or not.

    I’m curious to see if GI irons truly benefit a higher handicapper or not.

    As a high handicapper myself I hate GI irons and find them to be a marketing ploy to get more players into golf. One of the biggest reasons people leave the game is because it is so hard to hit the ball. GI irons make it easy, but it doesn’t make you better.

    I maintain this view because I see my game progressively improving year after year, while I see my buddy struggling to get better. We both started playing at the same time. he went the GI route, and can’t chip, pitch, and has no accuracy at all under 100 yards. On the other hand I am very accurate and very good and chipping and pitching when you consider we are both handicapped in the 20s. With every iron I am far more accurate and consistent than my buddy. I play MP-60s.

    Very surprised that there is not a larger gap in distance since the JPX 6 iron is 2 degrees stronger than the MP series. To be fair the MP5 does not behave like most blades and is much larger than any other blade offering from Mizuno. I feel that it is way more forgiving than any other MP I have seen outside of the H series. I agree with the earlier comment, I would like to see this test with an MP15 or even a MP4. Those are the last of the compact head, thin top line Mizunos. If not Mizuno test the Titleist MB or Callaway x-forged. It would be fun too for Mark to hit an 11th shot where he tries to “step on it”.

    This is interesting and I have 2 different views. Being a scratch+ golfer (as I assume Mark is as well) there is no need for me to hit game improvement irons, as I strike the ball in the center of the face more often than most. However, I performed a similar test with taylormade mb irons vs the new PSI forged. I found the PSI’s traveled about 8 yards further on average (after 20+ shots with each) and had just about the same amount of feedback. The spin rates were also very similar, with the main difference being the ball speed and launch angle. Both clubs had X100 Tour Issue shafts and were identical in every way outside of the head obviously. The 8 iron of the blade I believe is 1 or 2 degrees weaker than the PSI, so it doesn’t shock me that it went a little further, but the big surprise was that it actually launched higher on average than the mb. So I think this discussion need to be separated into 2 categories: 1. Players cavity vs blades for low handicappers and 2. GI vs standard/players cavity for higher handicappers. Players cavity irons are the wave of the future as more pros are moving away from blades. The thing that has changed is the feedback we get from the cavity irons is better than ever, and feedback is one of the only reasons I played blades in the past.

    An interesting side study to this would be if there was a way to test players hitting crucial shots in their club championship or other tourney to see how often they can hit the center of the club face under pressure. That brings me to my final thought: confidence. You should hit an iron you feel looks good and sets up well at address. Never choose an iron based on the so called benefits alone. If a thin top line makes you feel better over the ball, you should probably play the mbs over the PSI forged. The few shots that matter greatly during a round (getting out of trouble, forced carry, green with water/sand) are influenced most by how a player feels in the situation. You’ll hit a good shot if you feel you’ve got the right club in your hand. Beyond that, what’s in between your ears is still more important than what’s in your bag.

        You must be joking! Check out his GameGolf profile. That calculates a GG handicap (which tends to be close to your real one) of +0.6. Bis average score is 73.7

    I switched from a players iron to a GI (Speedblade) after about a year of having kids. I had no time to practice and my ball striking suffered. When i made the switch my 1 round per week became a lot more enjoyable and the scores came down significantly.

    I have been as low as a 5 index (pre-kids) and climbed over 12 once the practice sessions were no longer an option. GI irons helped me quickly get back to a solid single digit.

    You can fawn over the blade, it’s beauty or whatever all you want, but the average person or the 12 handicap is going to see improvement with GI irons.

    God bless technology!

      I beg to differ. I play MP-60s and my buddy plays RocketBladez. My shots are far more accurate and far more consistent than he has every been. We both started playing at the same time, and both our handicaps are in the 20s.

      there are shots he can’t make and won’t make because he isn’t comfortable with it, or doesn’t know how to do it. For me, there is nothing I can’t hit or do. Call that confidence vs club, but the theory that GI irons will benefit is a total falicy. It is a gimmick to get people to play the game by offering an easier to hit club. Is it easier to hit? Absolutely, but it doesn’t make you a better player. If you want to get better and be a better player, I maintain, even as a high handicapper, stay away from GI irons.

        I have to disagree with you Hawk…I did the same thing as Daddy Divots…combo blade set(McGregor V-foil yr 2002 when they were good) to the X-Hot pros by Callaway. I had the same thing happen to me since I didn’t play as much, from 6-7 times every month to 3-4 times with 2 months off. My handicap was going up to 9-10 range from 4-5. Most of the issues was not hitting enough greens from 170-210 range. Since I made the change…dropped back down again. One of my playing buddies is about the same handicap as you and he plays they same no mater what clubs are in his hands, his clubs.. to mine to a friends extra set of blades.
        I do think that this problem helps someone in the 5-12ish handicap range more then someone in your range.

        Honest Question, if you both you and your friend started at the same time and you can hit shots he can’t… and as you said..”On the other hand I am very accurate and very good and chipping and pitching when you consider we are both handicapped in the 20s”
        Have you considered that if you used GI clubs you would be in the teens?

    Nice video and is pretty spot on. A player does not intentionally aim for the toe no matter how high a handicap. A high handicapper is inconsistent in where they hit the golf ball on the face so even if they had a game improvement iron, it would not improve their outcome.

  8. Tony Wright

    Apr 17, 2016 at 5:35 pm

    Mark interesting test thank you. Is there any chance you could duplicate the test by hitting the EZ club with the same shaft you use in your MP5 clubs – Dynamic Gold S300? The XP 95 shaft is about 35 grams lighter than the Dynamic Gold shaft, and the XP 95 shaft flex profile throughout the shaft is a lot softer than the Dynamic Gold shaft flex profile. Would that make a difference, who knows unless you do it with the same shaft. All the best.

    So a scratch golfer finds little difference between a blade and a shovel on Trackman. Shocking. Have a 14 handicapper do the same comparison, and watch the blade numbers go sideways.

    • jcorbran

      Apr 17, 2016 at 3:52 pm

      14? average golfer shoots 100, that’s a 28ish. You didn’t hit anything thin or fat, test those clubs while chunking them all, see what works better.

    I recently demo’d the new Titleist 716 irons and the best performer for me was the CB hands down. AP1 were a little bit longer, as you’d expect with the stronger lofts, but those CB’s were going as far as the AP2 and T-MB irons (despite their lofts being a tad stronger) yet felt way more pure. On mis-hits I noticed exactly the same impact to the shot with all the irons, so it really is a no-brainer for me that the CB was what I’d bag from that line. If you can consistently strike the ball then why not play an attractive club like a CB or MB?

    • golfraven

      Apr 20, 2016 at 4:36 pm

      I agree here with you. The only clubs I would consider now are the CBs, even if the AP2 might be the better fit. Maybe even a combo of MBS and CBs but I guess this is just being funky.

    I’m surprised a hot faced iron isn’t flying a lot farther than a solid faced blade. Seems to for me in the long irons, but what do I know. Thanks for the review Mark.

    Apr 17, 2016 at 12:02 pm

    Very nice Mark. For a number of years I believed I should leave my old blades in the basement because no one can hit them but the pros. I never went full on GI irons I would buy the cavity back cut slot type of iron that I just didn’t really like the feel of. After breaking out my old Wilson Staff blades and hitting many buckets side by side with the cavity back irons like you I could not find any real meaningful difference.
    I hit my irons well but by no means am I a scratch golfer.
    I have to miss hit pretty baddly to really see a difference and a bad strike with any iron is a bad strike.
    I do feel like if mfgs. can convince us that all these different irons will make a difference they will sell more irons. It just make sense if you have six different irons to sell that a golfer will find something in your line they like or think will help them. I’m sure there are golfers that walk in the store and just look at GI irons because that’s what they think they can hit and never look at anything else they might enjoy more. Just think if Titleist made one kind of iron and said “This is the perfect iron” even if it was they would never sell as many. I’m not saying everyone should play blades I play Wilson FG Tour V2s because I like their feel and I know how far it will go when I hit it well but they are never HOT. Blades are not as hard to hit as some would have us believe. I must say I’m glad to see you playing the MP-5s I was a little bummed when you were playing the GI irons.

    I recently went from MacGregor player cavities to MP-59. I tried more game improving irons like XR, XR Pro, but unfortunately I can’t even look at those large heads with the thick top line. Sorry, but look of the head at address is important for me. The MacGregors just spoiled me in that category.

    Thank you for being the voice of reason Mark. If you hit it out the middle it doesnt matter what you play and “forgiveness” is mostly a marketing tool. Now Guru tell them all about shaft flex! #the truth is out there

    Mark, love your work. Anyone who gives me the drive to go back to blades is alright with me. Would like to see this test done with a 15 marker or something like that. Would be keen to see if there was a similar lack of difference. Cheers

    Crossfield says: “We should all just have one ball, one shaft, one head type. And call it a day. Because it’s the Indian and the arrow. All the time. If you know how to strike the ball, you’ll figure it out. I hate all these shaft choices. “

  19. Jordan Speeth

    Apr 16, 2016 at 7:32 pm

    I’ve experienced the same and, as a result, have gone back to a much more blade-y iron (Srixon Z745). If anything, they make me more aware of the fact that I want to/need to strike the ball with the center of the club face and, as a result, I do. The feel, performance, spin control, etc. though, are much better with the Z745 than the GI club in the range. I do have a Z545 4 iron with a stiff Graphite shaft and I think that club carries the ball significantly further than the steel shafted Z745 that would be part of my normal set. It REALLY takes off like a rocket…the Cavity/slot back Z545, that is. Anyway, I find myself agreeing with Mark and the type of player who would supposedly benefit greatly from a GI club, i.e.. 60+ years old, cancer patient (loss of strength/swing speed), losing eyesight/hand-eye coordination but all those factors considered, I’m still a better player with the blades. I was a Ping guy for two decades too. I sometimes play with a vintage set of Haig Ultra blades too, a REAL blade, and I can say that, though they’re still great, contemporary blades are not your grandfather’s clubs. They ARE easier to hit than 50s thru 70s butterknives.

    Play VR Pro blades after Titleist 690.mb’s, best golf of my life after many years of “player cavities.” Connection = feedback = improvement = results. It’s a smarter cycle. Few are aware!

5 men who need to win this week’s Open Championship for their season to be viewed as a success

Published

on

The year’s final major championship is upon us, with 156 players ready to battle it out at Royal Portrush for the Claret Jug. The oldest tournament in the sport presents the last opportunity for players to achieve major glory for nine months, and while some players will look back at this year’s majors and view them as a success, others will see them as a missed opportunity.

Here are five players who will tee it up at The Open, needing a win to transform their season, and in doing so, their career.

Adam Scott

Adam Scott has looked revived in 2019 with four top-10 finishes, including a T7 at the U.S. Open and a T8 at the PGA Championship. The Australian hasn’t won since 2016, and at 39-years-old, Scott knows better than anyone that the final narrative over his career comes down to whether or not he can add to his lone major championship victory he achieved at the 2013 Masters.

Speaking following his final round at Pebble Beach last month, Scott stated

“I’m angry; I want to win one of these so badly. I play so much consistent golf. But that’s kind of annoying; I’d almost rather miss every cut and win one tournament for the year if that win was a major.” 

A gut-wrenching finish cost Scott the Claret Jug at Royal Lytham and St. Annes seven years ago, and the 39-year-old has held at least a share of the back-nine lead on Sunday on three occasions at the event since 2012. The Australian’s statement following the U.S. Open says it all; a successful 2019 depends on whether or not he can finally put his Open Championship demons to bed.

Dustin Johnson

With a win in Mexico earlier this year, Dustin Johnson has now made it 11 straight seasons with at least one victory on the PGA Tour. However, Johnson continues to be judged, rightly or wrongly, on his struggles to capture major championships. The 35-year-old remains on one major victory for his career, which is a hugely disappointing total for a player of his talent.

Should the American remain stuck on one major for another nine months following this week’s event, it’s hard to imagine the 35-year-old feeling satisfied. Johnson came to Pebble Beach last month as the prohibitive favorite and failed to fire, but it’s what occurred at the PGA Championship which will leave a sour taste. With Brooks Koepka feeling the heat, Johnson had the opportunity to step up and reverse his major championship fortune, but two bogeys in his final three holes just added to his ‘nearly man’ tag at the most significant events.

A win in Northern Ireland removes both the ‘nearly man’ and ‘one major wonder’ tags, and turns his least successful season, victory wise, into one of his best.

Rory McIlroy

Whatever happens this week at Royal Portrush, Rory McIlroy’s season has been impressive, but it’s missing something big. That something is a win at a major championship, and it’s been missing since 2014. To avoid a five-year drought at the majors, McIlroy must win the 148th Open Championship at home, and with it, claim the greatest victory of his career.

Speaking prior to this week’s tournament, McIlroy stated

“I want to win for me. It’s not about trying to do something in front of friends and family.”

The home-town hero is currently in the midst of one of the greatest ball-striking seasons of all time. But without a win at a major to show for it, there’s undoubtedly going to be frustration and regret in the aftermath. On the flip side, should the Ulsterman triumph this week then it would likely eclipse his double major season success of 2014, and according to the man himself, it would also eclipse anything that he could ever go on to achieve in the game thereafter.

Rickie Fowler

Without getting his hands on a major, the narrative behind Rickie Fowler is not going to change. ‘The best player without a major’ tag has been there for a while now with Fowler – who hasn’t been close to shaking it off in 2019. Victory at the Phoenix Open back in February snapped a 24-month streak without a win on the PGA Tour, but you’d be hard-pressed to find anyone considering the 30-year-old’s season a success without him finally getting the monkey off his back and entering the winner’s circle at a major.

Justin Rose

Justin Rose turns 39-years-old this year, and each season from now to the house, he will be judged on his success at the majors. With  wins at the U.S. Open and Olympics already achieved in his career, a successful season for the Englishman now depends on whether he can become a multiple major champion.

Talking ahead of his bid to win his first Open Championship, Rose said

“People don’t come up to me and say, ‘Hey, you won the FedEx!’. It’s the US Open, the Olympic gold, the Ryder Cup. I’m 40 next year and yes, the clock is ticking.

I’ve had three top threes in the majors in the last three seasons, with two seconds, so I know I’m right there doing the right things. It’s just a case of making it happen again, because the chances won’t keep coming forever.”

Rose’s sense of urgency may stem from tough losses at the 2017 Masters, 2018 Open Championship and more recently at the 2019 U.S. Open. In Rose’s favor is that the average age of winners of The Open since 2011 is almost five years higher than the average age of those who won the Masters, and over eight years older than those who won the U.S. Open. To elevate his 2019 to elite levels, Rose is relying on victory at Royal Portrush.

Opinion & Analysis

From the GolfWRX Vault: The day I met Ben Hogan

Published

on

In addition to continuing to look forward to new content that will serve and engage our readership, we also want to showcase standout pieces that remain relevant from years past. In particular, articles with a club building or instruction focus continue to deliver value and convey useful information well after their publish dates.

We want to make sure that once an article falls off the front page as new content is covered it isn’t relegated to the back pages of our website.

We hope that you’ll appreciate and find value in this effort.

Industry veteran (and one heckuva writer) Tom Stites, who served as the Director of Product Development at Nike’s Oven, tells the story of how he landed a job as an engineer at the Ben Hogan Company and what his first meeting with Mr. Hogan was like.

Get a taste for Stites’ excellent piece from 2015 below.

Getting near my boy was the real reason I wanted to get to Texas, but the golf was a sweet attraction, too. With a perfect touch and timing, the Good Lord prompted the Hogan Company to advertise for a new product development engineer. On just the right day, I was changing flights at DFW and bought a copy of the Fort Worth paper. In the want ads I saw something like, ”Ben Hogan will pay you cash money to engineer and work on golf clubs.” So I applied.

My product development experience at Kohler got me the interview, but the Good Lord got me the job. It was truly a real miracle, because in 1986 I knew zero about club design and manufacturing. I was quickly made the boss of the model shop, and was to manage the master club maker Gene Sheeley and his incredible team of long-time club artisans.

Me as their boss? That was a joke.

I knew a few things about physics at that time, but these guys were the real deal in club design. I knew immediately that I was in over my head, so I went to Gene and professed my ignorance. I pleaded with him to teach me how to do the job right. At that, I guess he considered me harmless and over the next number of years he became my Yoda. His voice was even a bit like Yoda.
