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.

      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.

    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. “

    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!

What’s old is new again

Published

on

All of a sudden, today’s newest trend in golf is yesterday’s clubs.

Golfers are making a move towards old classics the way car enthusiasts would ogle a classic Porsche 911 before they would look twice at a new Tesla Model 3. On the spectrum of art to science, Tesla is peak science and focused on efficiency in every fathomable way. The other will absolutely get you from A to B, but you are more likely to have a smile on your face while you take the detour along the water while enjoying the journey to get there. It is the second type of club that is enjoying this latest resurgence, and I can’t get enough.

New businesses are springing up to refurbish old clubs such as @mulligansclubmakers and @twirledclubs with price tags approaching (and exceeding) the RRP at the time of release of many of the clubs in question. These old clubs are often found in pictures of major champions being used in the 1970s and 1980s, which serves to make them more valuable and interesting to enthusiasts. Other clubs are simply polished examples of the clubs many of us owned 25 years ago and now regret selling. The more polish on an old blade, the better, with classic designs from brands like Wilson Staff, Mizuno, or MacGregor seeing demand and prices increase every month. Seeing these old clubs reimagined with shiny BB&F co ferrules, updated shafts, and grips can get some golfers hot and bothered, and they will open their wallets accordingly.

Around 15 years ago, I bought an old set of blades from the brand Wood Brothers. For many years, I was unable to find out a single thing about those clubs, until @woodbrosgolf came out of hibernation this year onto Instagram and into a frothing market for handmade classic clubs from a forgotten past. I was able to get information that the blades had come out of the Endo forging house in Japan, and my decision to keep the clubs in the garage all these years was vindicated. Now I just need an irrationally expensive matching Wood Bros persimmon driver and fairway wood to complete the set…

Among other boutique brands, National Custom Works (@nationalcustom) has been making pure persimmon woods with the help of Tad Moore to match their incredible irons, wedges, and putters for some time, and now the market is catching up to the joy that can be experienced from striking a ball with the materials of the past. There is an illicit series of pictures of persimmon woods in all states of creation/undress from single blocks of wood through to the final polished and laminated artworks that are making their way into retro leather golf bags all over the world.

There are other accounts which triumph historic images and sets of clubs such as @oldsaltygolf. This account has reimagined the ‘What’s in the Bag’ of tour pros in magazines and made it cool to have a set of clubs from the same year that shows on your driver’s license. I hold them wholly to blame for an impulse buy of some BeCu Ping Eye 2 irons with matching Ping Zing woods… The joy to be found in their image feed from the 70s and 80s will get many golfers reminiscing and wishing they could go back and save those clubs, bags and accessories from their school days. If you want to see more moving pictures from the era, @classicgolfreplays is another account which shows this generation of clubs being used by the best of the best in their heyday. Even better than the clubs are the outfits, haircuts and all leather tour bags to match.

It seems that this new generation of golfer – partially borne out of COVID-19 — is in need of clubs that can’t be sourced fast enough from the major OEMs, so they have gone trawling for clubs that were cool in a different time, and they want them now. Those golfers who match the age of the clubs are also experiencing a golfing rebirth, as the technology gains from the OEMs become incremental, many are now finding enjoyment from the classic feel of clubs as much as they are searching for an extra couple of yards off the tee.

Either way, the result is the same, and people are dusting off the old blades and cavities from years past and hitting the fairways more than ever before. With the desire shifting towards fun over challenge, they are even creeping forward to the tees that their clubs were designed to be played from and finding even more enjoyment from the game. If only I hadn’t got rid of those old persimmons in high school…

The Wedge Guy: Top 4 reasons why most golfers don’t get better

Published

on

A couple of years ago, I attended a symposium put on by Golf Digest’s research department. They explored the typical responses as to why people quit or don’t play more – too much time, too expensive, etc. But the magazine’s research department uncovered the real fact – by a large margin, the number one reason people give up the game is that they don’t get better!

So, with all that’s published and all the teaching pros available to help us learn, why is that? I have my rationale, so put on your steel toe work boots, because I’m probably going to step on some toes here.

The Top 4 Reasons Golfers Don’t Improve

  1. Most golfers don’t really understand the golf swing. You watch golf and you practice and you play, but you don’t really understand the dynamics of what is really happening at 100 mph during the golf swing. There are dozens of good books on the subject – my favorite is Ben Hogan’s “Five Lessons – The Modern Fundamentals of Golf.” But pick any good one and READ IT. LEARN IT. It will help you immensely if you understand what the swing is really all about. Use a full length mirror to pose in key positions in the swing to match the drawings and photos. All the practice in the world will not help if you are not building a sound fundamental golf swing.
  2. Learning golf doesn’t start in the middle. A sound golf swing is built like a house. First the foundation, then the framing, roof, exterior walls, interior, paint, and trim. You can’t do one before the other. In golf, it all starts with the grip. If you do not hold the club properly, you’ll never accomplish a sound golf swing. Then you learn good posture and setup. If you don’t start in a good position, the body can’t perform the swing motion properly. With a good grip and a sound setup posture, I believe anyone can learn a functional golf swing pretty easily. But if those two foundations are not sound, the walls and roof will never be reliable.
  3. Most bad shots are ordained before the swing ever begins. I am rarely surprised by a bad shot, or a good one, actually. The golf swing is not a very forgiving thing. If you are too close to the ball or too far, if it’s too far forward or backward, if you are aligned right or left of your intended line, your chances of success are diminished quickly and significantly. The ball is 1.68 inches in diameter, and the functional striking area on a golf club is about 1.5-inches wide. If you vary in your setup by even 3/4 inch, you have imposed a serious obstacle to success. If you do nothing else to improve your golf game, learn how to set up the same way every time.
  4. Learn to “swing” the club, not “hit” the ball. This sounds simple, but the golf swing is not a hitting action: it’s a swinging action. The baseball hitter is just that, because the ball is in a different place every time – high, low, inside, outside, curve. He has to rely on quick eye-hand coordination. In contrast, the golf swing is just that – a swing of the club. You have total control over where the ball is going to be so that you can be quite precise in the relationship between your body and the ball and the target line. You can swing when you want to at the pace you find comfortable. And you can take your time to make sure the ball will be precisely in the way of that swing.

Learning the golf swing doesn’t require a driving range at all. In fact, your backyard presents a much better learning environment because the ball is not in the way to give you false feedback. Your goal is only the swing itself.

Understand that you can make a great swing, and often do, but the shot doesn’t work out because it was in the wrong place, maybe by only 1/4 inch or so. Take time to learn and practice your swing, focusing on a good top-of-backswing position and a sound rotating release through impact. Learn the proper body turn and weight shift. Slow-motion is your friend. So is “posing” and repeating segments of the swing to really learn them. Learn the swing at home, refine your ball striking on the range and play golf on the course!

So, there you have my four reasons golfers don’t get better. We all have our own little “personalization” in our golf swing, but these sound fundamentals apply to everyone who’s ever tried to move a little white ball a quarter-mile into a four-inch hole. Working on these basics will make that task much easier!
