Are you a candidate for a driving iron?

Published

on

A few weeks ago I wrote an article comparing the performance of my 5 wood, hybrid and 3 iron on Trackman to better understand the pros and cons of each club.

It wasn’t that hard to guess that the 5 wood flew higher, carried farther and landed softer than the rest. What was very eye-opening to me was the lack of height my 3 iron produced. It flew much lower than the PGA Tour Average, and its lower flight is the sole reason why I no longer carry a 3 iron. It comes out too flat and runs when it hits the ground, and that’s not a good trajectory for hitting shots into a green. That’s also why my hybrid has been so valuable to me. Like my 5 wood, it flies higher and lands softer.

While I know that hitting long irons into the greens is not optimal, what about using one primarily off the tee? Also, what about golfers who play in windy conditions? Are they better off with a long iron?

Since this is British Open week, I thought it would be a good idea to examine these questions for my readers on GolfWRX.

The wind is known to be a factor in the UK and many other places like Texas and Oklahoma, so the high-flying shots I hit with a hybrid and 5 wood are probably not the best option if you play golf in those conditions. So if you cannot use your fairway woods and hybrids into the wind with success, what should you do?

The answer is to employ a “driving iron,” a club that is nothing new to most golfers. Their updated designs, however, have made these clubs super easy to hit unlike the driving irons of the past. If you keep up with new golf equipment releases like most GolfWRXers do, you’ll notice that several companies have released new driving irons and I think they can make a big difference in certain goflers’ games.

First, a little background. Driving irons are bulked-up players irons that are designed to hit the ball higher and farther than standard 1, 2 or 3 irons. Their trajectory will be lower than most similarly lofted fairway woods and hybrids, however, their lower launch angles and landing angles lead to a huge amount of roll. That’s perfect for windy conditions and fast, firm fairways.

The latest driving iron to be released is TaylorMade’s new UDI, which stands for “Ultimate Driving Iron,” and the company was kind enough to send me a 1 iron and 2 iron ahead of time so I could test them on Trackman and explain why a driving iron may or may not be a good fit for your game.

See what GolfWRX Members are saying about TaylorMade’s UDI in our Official Testing Thread.

For this test, I will be using a UDI 1 iron that measures 16 degrees as well as a UDI 2 iron that measures 18 degrees. Both clubs are built to standard length (39.75 inches in the 1 iron, 39.25 inches in the 2 iron) and have Oban’s Kiyoshi Purple 100-gram hybrid shaft in stiff (04) flex.

The first 10 shots with each club were hit off a tee. I hit the next 10 shots with each club off the ground hitting “stingers,” low-trajectory shots that simulate the shots many pros will be hitting off the tee when necessary this week.

An important note: The roll data in the Trackman screenshots below is calculated using the average amount of roll on PGA Tour fairways that Trackman has gathered since 2003.

Here’s what the data says.

UDI 2 iron hit from a small tee

Driving Iron 1

  • The clubhead speeds were between 93.7 mph and 95.1 mph giving me carry distances that ranged from 225.4 to 239.9 yards.
  • The average height was 87 feet in the air with an average spin rate of 5151 rpm.
  • As you can see, the landing angles are still flat enough for some run out even at this height. The average 35.2-degree landing angle created an average roll of 22.8 yards.
  • What is nice to see is that the height is up, the spin is manageable and yet the landing angles are still pretty flat. That means we are not losing any distance when the ball is teed up

UDI 2 iron “stinger” from the ground

Driving Iron 2

  • The club head speed for the two different shots (full swing from a tee and stinger from the ground) is basically the same. I averaged 1.3 mph more club head speed hitting “stingers,” so that gave me a touch more ball speed on shots I hit solid.
  • The spin rate dropped from 5151 rpm to 4990 rpm on these stinger shots off the ground, which gave me a feeling of more compression (or a lower spin loft) due to the decreased dynamic loft.
  • The average dynamic loft for the “normal” shot was 16.7 degrees while the stinger was 12.1 degrees.
  • These balls almost carried the same distance, but when you chart the landing angle you can see that the stinger landed at 29.7 degrees. That’s 5.5 degrees less than shots of the tee, which gave me more roll.
  • If we take out shot No. 6, which was a mis-hit that spun too much, the average total distance increased to 257.8 yards. That shows that lower, more driving shots hit with less spin will tend to chase forward more with these clubs than stock shots.

UDI 1 iron hit from a small tee

Driving iron 4

  • The club head speed went up with the 1 iron due to its 0.5-inch length, but not by much. I averaged 96.5 mph compared to 94.5 mph and 95.8 mph with the 2 iron.
  • The spin rate dropped slightly to 4467 rpm with the 1 iron, but the height went up slightly to 90 feet.
  • The carry ranged from 228.4 yards to 253.5 yards. As you can see, there were a few “jumpers” that carried 250 yards, but that isn’t much farther than the 241-yard average.
  • The landing angles are once again around 35 degrees, which gives us a nice amount of roll out even with the higher trajectory.
  • As the swing speed increases and loft lowers, you will tend to see some added side-to-side dispersion. What’s nice is that none of these shots are off the planet. That’s a testament to the forgiveness built into these clubs.
  • In regard to the carry distances being a touch volatile at 25.1 yards, I did hit one funky shot at 228.4 yards. Taking that one out would give us a carry dispersion of only 18 yards. That’s not bad with a 1 iron.

TMAG UDI 1 iron “stinger” from the ground

Driving Iron 5

  • As we lower dynamic loft, the height of the shot will decrease. That requires a higher ball speed in order to carry the ball as far. The average dynamic loft on the stock 1-iron shot was 15.9 degrees, while the average dynamic loft of the 1 iron stinger was only 10.1 degrees with a relatively minor ball speed increase of 2.3 mph. That’s why the ball did not carry as far with the 1 iron stinger shot as it did with the stock shot.
  • When you drop the spin and lower the dynamic loft, you will tend to lose height (90 feet with the stock 1 iron shot, 55 feet with the 1 iron stinger), but you can make up for this in roll if the conditions are right through the lower landing angle. In this case, the 1 iron stinger’s average landing angle was 26.4 degrees, about 9-degrees lower than the stock 1 iron shot.
  • The roll out for the stock 1 iron shot was 24.3 yards, but the stinger gave me 36 yards of roll. So if you’re trying to avoid the wind and use firm fairways to chase the ball forward you have your club (a UDI 1 iron) and your shot type (a stinger).
  • I did hit one stinger that was a rocket. It carried 245.7 and gave me a total distance of 275.7, which says if you can catch these irons just right they will really, really GO!

Let’s summarize

Driving iron 7

  • You will see very little clubhead speed differences between the two clubs because they are not that much different in length.
  • The technology built into the driving irons of today — a little more offset, “Speed Pockets,” thin faces and low center of gravities, etc. — are a must to make these clubs much easier to hit than you’d think they would be. This is the reason that today’s driving irons are a great choice for the better player who plays in conditions that warrant such a club.
  • The UDI 2 iron was a comfortable 230 carry for me at altitude while the UDI 1 iron gave me 240 yards of carry. As you look into your own game, you must figure out where this club fits into your set. Sometimes a club that carries 230 yards and rolls to 250 yards is the ticket, while other times a club that carries 240 yards and rolls to 260 yards is better. Monitor your gaps to choose the right club.
  • I did hit a few shots with the UDI out of the rough, but if you don’t have at least an average lie you will see flatter than normal trajectories from these driving irons.
  • When hit from a “jumper” lie, these clubs are like magic. They go high and far with the feeling of more control just like an iron.
  • You must practice hitting the stinger shot with these clubs. If you do not have the ability to decrease your dynamic loft and hit a low runner, you are missing a key shot that these irons can add to your game.

Finally, and maybe most importantly for the readers looking to buy a driving iron, don’t let your ego become a part of your loft decision. Some golfers will get better numbers with a UDI 3 iron (20 degrees) than they will a UDI 1 iron or 2 iron and that’s great. Buy the club that will help your game the most, not what will look the coolest in your bag.

    To me it all depends on how you attack the ball. Hybrids and long irons still require a bit of downward contact which will be different from say your 3 wood or 5 wood. I loved my udi 2 and 3 but realized that my 3 iron was just as good as the 3 udi and my Sldr hybrid allowed for me to lift up or down if needed which I often do depending on the length of the course I am playing. Now I rotate between carrying a hybrid at all to carrying an extra wedge. The udi driving irons are real easy to hit and with the lower center of gravity have an easier time getting the ball up higher. Just like anything else, it’s the individual players taste and I highly recommend testing out the driving irons or go to the bst and probably can grab one in the !70 dollar range. If you love hitting the longer irons of your bag then the driving irons are your preferred clubs. If you don’t carry more than a 5 iron. I suggest possibly trying a hybrid which offers a thicker sole or ultimately grabbing a 7 and 5 wood instead.

    A review versus a standard 2-iron would also be appreciated. I see McIlroy went with the prototype Nike driving iron, where Tiger stayed with his VRS 2-iron. It’d be interesting to see the distance/flight differences. I currently have an MP63 3-iron as well as a 3-iron bent to 18 degrees a half inch longer than my other 3. Never liked the look of the new Mizuno driving irons though, but would still like to see what, if anything i’m missing out on… And would i be better off investigating getting a proper one

    Always had trouble hitting hybrids, more so off the tee than the turf. Snap hooks and a ballooning ballflight. Went on a recommendation and purchased the Mizuno MP-H4 3 iron with a DG X100 soft stepped shaft. It is easily the my best performing club in the bag, and my favorite club in the bag. Most par 5s are reachable in two and with the confidence of hitting an iron rather than 3 wood. For anyone looking for a (mostly) forgiving driving iron option, give the MP-H4 a try. Very versatile club, and workable whether off the tee or off the turf.

    There are already a lot of driving irons on the market so if you want one you do not necessarily have to get TM’s new one. I had a Cleveland LDI 15 degree in my bag for the longest time to replace my 3 wood because not only could I hit it lower than the wood, I could also hit it higher if I wanted and I could control it much better. There are also many other driving irons by all the other manufactures.

    Not sure if I love “jumpers” off the face. Nothing a good player hates more than inconsistent distance control with a club meant to find fairways and/or lay up short of hazards.

    Catching a 275yd jumper is no good when you need 265 to stay short of a 270-275 yard hazard is no good.

    Just received this from TM support: “The 2 and 1 UDI are going to be 18 and 16 degree lofts. They are going to have a higher trajectory than the Rocketbladez Tour irons. The UDI will be a longer 2 iron than the Rocketbladez Tour. It is built with driver DNA.

    Jul 16, 2014 at 9:57 am

    Great review. How would you compare the UDI to older, but still similar driving irons like the Airmuscle? I am currently gaming the 2+3 airmuscles, but do have some trouble hitting them consistently off the turf. I use them almost solely from the tee as I currently don’t play a driver due to bad inconsistency.

        Last year I played at Los Cerros Golf Club in Quito, Ecuador 9350 ft. Almost impossible to breath but very rewarding on driving the ball. More than 300 yds!!! At sea level I struggle to reach 250. I was imagining Jamie Sadlowski playing there.

    Jul 15, 2014 at 9:29 pm

    Tom,

    I having trouble figuring out where I would put one of these in my bag. My distances are as follows:

    Driver: 290
    3 wood (15)- 250
    Hybrid (20)- 230
    4 Iron- 212
    5 Iron- 200

    I struggle to hit my hybrid so I would like to add a driving iron. Do you have a recommendation as to what I could take out and what loft?

    • tom stickney

      Jul 16, 2014 at 12:40 am

      You might want to try the 18 degree udi 2 iron…you’d have a gap between your 4 and your 2 and you’d have to work around it…experiment

      • Adam B.

        Jul 16, 2014 at 1:08 am

        Would you take out the hybrid or 3 wood? I feel like I would hit the UDI 2 iron just as far as my 3 wood. Wouldn’t it be better to go with the UDI 1 and just take out my 3 wood?

        • CodenameDuchess

          Jul 17, 2014 at 2:57 pm

          You said you struggled with the hybrid why would you remove your 3 wood? You need to find a club that flies 230ish so you can kick the troubling hybrid out of the bag.

          Check out the MP-H4 long irons. They make a 2 & 3 that are basically driving irons. Ping, Titleist & Callaway all make driving irons too. Find the one that you hit 225-230 and you’re gold.

    I find it difficult to use any hybrid for some reason. My ball striking isn’t bad with any other club except the hybrid. I tend to love these low lofted 3 irons as I carry a Speedblade as my DI now, with a flighted PX shaft. Do you think shaft selection (graphite vs steel) plays a role in this?

    • Tom Stickney

      Jul 15, 2014 at 7:08 pm

      Could be. Not sure without seeing your motion. If suggest a fitting to be sure.

      Jul 16, 2014 at 12:44 pm

      I have similar challenges. The current range of hybrids such as the RBZ Stage 2 Tour and similar items from the large manufacturers look like pseudo-woods. I’ve never had good luck with fairway metals, be they from Adams or Exotics. The hybrids aren’t helpful to me either and I think it’s largely about the “optics”. Something you may explore (if only because I found it helpful), is returning to more of a “true” hybrid. From a purely optics perspective, something like the Adams DHY Proto strike me as less bulky and more in keeping with the notion of a what a hybrid should be: something between an iron and a fairway metal. In contrast, most of what passes for a hybrid now appears to lean heavily toward actually being a fairway metal, albeit somewhat more compact, and has less resemblance to an iron with each passing product release.

    Just this morning I took a Callaway FT 2 iron to test it against my Callaway X-Hot pro 2 hybrid. Also as expected the 2 hybrid went higher, farther, and stopped faster than the 2 iron. I am apparently not a candidate for a driving iron.

    So Tom I’m looking at these and thinking they’re probably great of the Tee or a nice flat perfect lie in the fairway, but much like a regular long Iron not so good from the ruff or a sever down hill or side hill lie. Am I right, because I find it hard to believe anything can really out perform my Adams Idea pro A12 20 degree and Adams Idea pro Black 22 degree from less than perfect lies?

    • Tom Stickney

      Jul 15, 2014 at 6:24 pm

      They are better off the tee/fairway giving you more control over your trajectory but most people are better off with hybrids if they don’t play in super windy conditions.

What to look for in a golf instructor: The difference between transformative and transactional coaching

Published

on

Golf instruction comes in all different styles, methods, and formats. With that said, you would think this would be a good thing due to there being so many different types of people in the world. However, it is my opinion that the lack of standardization within the industry makes it confusing for the athlete to determine what kind of golf instruction they should seek out.

Before we can discuss what may or may not be the best type of instruction for yourself, first we need to know what our options are. Whether we are taking a “broad-spectrum approach” to learning or a more personalized approach, it is important to understand that there are differences to each, and some approaches are going to take longer than others to reach goals.

Broad-Spectrum Approach

Welcome to the world of digital golf instruction, where tips from the most famous coaches in the world are a click away. The great thing about the internet and social media for a golfer is there has never been more access to the top minds in the field—and tips and drills are plentiful. With that said, with there being so many choices and differing opinions, it can be very easy to become distracted with the latest tip and can lead to a feeling of being lost.

I would describe “internet coaching”—or YouTube and Instagram surfing—as transactional coaching. You agree to pay, either a monthly fee or provide likes or follows and the professional provides very generalized tips about the golf swing. For athletes that are new to golf or golf instruction, this tends to be the first part of their process.

There are people who prefer a more transactional approach, and there are a ton of people having success working together over the internet with their coach. With that said, for someone who is looking for more of a long-term individualized approach, this may not be the best approach. This broad-spectrum approach also tends to be the slowest in terms of development due to there being a lot of trial and error due to the generalized approach and people having different body types.

Individual Transactional Coaching

Most people who are new to golf instruction will normally seek out their local pro for help. Depending on where you live in the country, what your local pro provides will vary greatly. However, due to it being local and convenient, most golfers will accept this to be the standard golf lesson.

What makes this type of instruction transactional is that there tends to be less long-term planning and it is more of a sick patient-doctor relationship. Lessons are taken when needed and there isn’t any benchmarking or periodization being done. There also tends to be less of a relationship between the coach and player in this type of coaching and it is more of a take it or leave it style to the coaching.

For most recreational or club-level players, this type of coaching works well and is widely available. Assuming that the method or philosophies of the coach align with your body type and goals athletes can have great success with this approach. However, due to less of a relationship, this form of coaching can still take quite some time to reach its goals.

Individual Transformative Coaching

Some people are very lucky, and they live close to a transformative coach, and others, less lucky, have had to search and travel to find a coach that could help them reach their goals. Essentially, when you hire a transformative coach, you are being assigned a golf partner.

Transformative coaching begins with a solid rapport that develops into an all-encompassing relationship centered around helping you become your very best. Technology alone doesn’t make a coach transformative, but it can help when it comes to creating periodization of your development. Benchmarks and goals are agreed upon by both parties and both parties share the responsibility for putting in the work.

Due to transformative coaching tending to have larger goals, the development process tends to take some time, however, the process is more about attainment than achievement. While improved performance is the goal, the periods for both performance and development are defined.

Which One is Right for You?

It really depends on how much you are willing to invest in your development. If you are looking for a quick tip and are just out enjoying the weather with your friends, then maybe finding a drill or two on Instagram to add to your practice might be the ticket. If you are looking to really see some improvement and put together a plan for long-term development, then you are going to have to start looking into what is available in your area and beyond.

Some things to consider when selecting a coach

  • Do they use technology?
  • What are their qualifications when it comes to teaching?
  • Do they make you a priority?

As a golf coach who has access to the most state-of-the-art technology in the industry, I am always going to be biased towards a data-driven approach. That doesn’t mean that you should only consider a golf coach with technology, however, I believe that by having data present, you are able to have a better conversation about the facts with less importance placed on personal preference. Technology also tends to be quite expensive in golf, so be prepared if you go looking for a more high-tech coaching experience, as it is going to cost more than the low-tech alternative.

The general assumption is that if the person you are seeking advice from is a better player than you are, then they know more about the golf swing than you do. This is not always the case, while the better player may understand their swing better than you do yours, that does not make them an expert at your golf swing. That is why it is so important that you consider the qualifications of your coach. Where did they train to coach? Do they have success with all of their players? Do their players develop over a period of time? Do their players get injured? All things to consider.

The most important trait to look for in a transformative coach is that they make you a priority. That is the biggest difference between transactional and transformative coaches, they are with you during the good and bad, and always have your best interest top of mind. Bringing in other experts isn’t that uncommon and continuing education is paramount for the transformative coach, as it is their duty to be able to meet and exceed the needs of every athlete.

The importance of arm structure

Published

on

How the arms hang at address plays a vital role in the golf swing. Often overlooked, the structure in which we place the arms can dictate one’s swing pattern. As mentioned in the article How Posture influences your swing, if you start in an efficient position, impact is much easier to find making, the golf swing more repeatable and powerful.

To start, I opt to have a player’s trail arm bent and tucked in front of them with angle in the trail wrist. While doing so, the trail shoulder can drop below the lead with a slight bend from the pelvis. This mirrors an efficient impact position.

I always prefer plays to have soft and slightly bent arms. This promotes arm speed in the golf swing. No other sports are played with straight arms, neither should golf.

From this position, it’s easier to get the clubhead traveling first, sequencing the backswing into a dynamic direction of turn.

@peterthomson

When a player addresses the ball with straight arms, they will often tilt with their upper body in the backswing. This requires more recovery in the downswing to find their impact position with the body.

A great drill to get the feeling of a soft-bent trail arm is to practice pushing a wall with your trail arm. Start in your golf set-up, placing your trail hand against the wall. You will instinctively start with a bent trail arm.

Practice applying slight pressure to the wall to get the feeling of a pushing motion through impact?. When trying the drill with a straight trail alarm, you will notice the difference between the two? arm structures.

What is ground force in the golf swing?

Published

There is no doubt about it, the guys and gals on tour have found something in the ground—and that something is power and speed. I’m sure by now you have heard of “ground reaction forces”—and I’m not talking about how you “shift your weight” during the golf swing.

Ground force in the golf swing: Pressure and force are not equal

With respect to ground force in the golf swing, it’s important to understand the difference between pressure and force. Pressure is your perception of how your weight is being balanced by the structure, in this case, the human body. Your body has a center of mass which is located roughly one inch behind the belt buckle for men and about one inch lower in women. When we shift (translate and/or torque) the center of mass, we create a pressure shift as the body has to “rebalance” the mass or body. This pressure shift can help us understand some aspects of the golf swing, but when it comes to producing power, force and torque are where it’s at.

Pressure can only be expressed in relation to the mass or weight of the body. Therefore, if you weigh 150 pounds, you can only create 150 pounds of pressure at one time. However, when we direct that mass at a larger object than our mass, all of a sudden that larger mass directs an opposite and equal reactionary force. So now, when a human being “pushes” their legs against the ground and “feels” 150 pounds of pressure, they now get 150 pounds of force directed back towards them from the ground, creating a total of 300 pounds of force that allows them to jump off the ground in this scenario.

If ground reaction forces don’t have anything to do with the “weight shift,” then what do they affect? Everything!

Most people use the same basic ingredients to make chocolate chip cookies. However, almost everyone has chocolate chip cookies that taste slightly different. Why is that? That is because people are variable and use the ingredients in different amounts and orders. When we create a golf swing, whether we are aware of it or not, we are using the same basic ingredients as everyone else: lateral force, vertical torque, and vertical force. We use these same three forces every time we move in space, and how much and when we use each force changes the outcome quite a bit.

Welcome to the world of 3D!

Understanding how to adjust the sequencing and magnitude of these forces is critical when it comes to truly owning and understand your golf swing. The good news is that most of our adjustments come before the swing and have to do with how we set up to the ball. For example, if an athlete is having a hard time controlling low point due to having too much lateral force in the golf swing (fats and thins), then we narrow up the stance width to reduce the amount of lateral force that can be produced in the swing. If an athlete is late with their vertical force, then we can square up the lead foot to promote the lead leg straightening sooner and causing the vertical force to happen sooner.

While we all will need to use the ground differently to play our best golf, two things need to happen to use the ground effectively. The forces have to exist in the correct kinetic sequence (lateral, vertical torque, vertical force), and the peaks of those forces need to be created within the correct windows (sequencing).

  • Lateral force – Peak occurs between top-of-swing and lead arm at 45 degrees
  • Vertical torque – Peak occurs between lead arm being 45 degrees and the lead arm being parallel to the ground.
  • Vertical force – Peak occurs between lead arm being parallel to the ground the club shaft being parallel to the ground.

While it may seem obvious, it’s important to remember ground reaction forces are invisible and can only be measured using force plates. With that said, their tends to be apprehension about discussing how we use the ground as most people do not have access to 3D dual force plates. However, using the screening process designed by Mike Adams, Terry Rowles, and the BioSwing Dynamics team, we can determine what the primary forces used for power production are and can align the body in a way to where the athlete can access his/her full potential and deliver the club to the ball in the most effective and efficient way based off their predispositions and anatomy.

In addition to gaining speed, we can help athletes create a better motion for their anatomy. As golfers continue to swing faster, it is imperative that they do so in a manner that doesn’t break down their body and cause injury. If the body is moving how it is designed, and the forces acting on the joints of the body are in the correct sequence and magnitude, not only do we know they are getting the most out of their swing, but we know that it will hold up and not cause an unforeseen injury down the road.

I truly believe that force plates and ground reaction forces will be as common as launch monitors in the near future. Essentially, a launch monitor measures the effect and the force plates measure the cause, so I believe we need both for the full picture. The force plate technology is still very expensive, and there is an educational barrier for people seeking to start measuring ground reaction forces and understanding how to change forces, magnitudes, and sequences, but I’m expecting a paradigm shift soon.
