Modern Irons

Modern irons hit the ball farther – that is true. But why?

A look at a recent 5 iron showed a loft of just 21 degrees. Combine this with a longer shaft length and that 5 iron you are holding is very likely just a 3 iron with a different number at the bottom.

Speaking with Kirk Oguri, golf professional/equipment specialist at Pete’s Golf Shop (NY), he explained;

Manufacturers have figured out how to get the center of gravity of the club much lower, resulting in a higher ball flights. This allows them to then deloft the clubs and still achieve the same peak height.

High launch and lower spin = crazy distance. (Find out more about that by reading THIS)

Also, face materials are springier, increasing something called coefficient of restitution (COR) – basically a measure of how fast the ball comes off the face.

Shot Patterns

When we hit an iron, we might

• Flush it
• Hit an average strike (perhaps 10 yards loss in distance)
• Have a slightly bigger miss-hit (perhaps 20 yards loss)

Sure, we can also duff it completely, but for most golfers who have been playing many years, most of their shots will fall into one of the above 3 categories.

And, no matter how good the irons are or how good the player is, no one flushes it all the time.

Hole Overlay

Imagine you are faced with the following scenario on the course.

The flag is 150 yards away. The player pulls out their 6 iron – the club they hit 150 if they flush it.

Now, let’s look at an overlay of their shot pattern

As we can see, when they flush it, they land in the green zone and have their birdie putts. The average strikes land in the yellow zone, and the slightly bigger miss-hits land in the red zone.

With The New Clubs

Now that the player is blasting it 20 yards farther with their new irons, they come to the same hole as before – 150 yards to the pin. This time, they use their 8 iron instead of their 6 iron.

Let’s have a look at their shot patterns.

No, I didn’t make a mistake and accidentally put the same picture – it is the same picture.

That’s right – the player will get some flushed shots which land in the green zone, a lot of average shots landing in the yellow zone, and some slightly bigger miss-hits landing in the red zone.

The pattern is essentially the same, even if they used an 8 iron to get there instead of a 6 iron.

But Aren’t New Clubs More Forgiving?

Great question – you caught me out, didn’t you……

Or did you?

While it is true that modern clubs have a higher resistance to twisting (moment of inertia) and larger sweet spots (resulting in more consistent distances on heel and toe hits), the clubs can’t offer any more forgiveness on a ground contact error.

What Is The COR Of Mud?

We have said that one of the reasons modern irons go so far is that they have a higher COR.

A golf ball might come off a modern club at 1.42 times the speed of the clubhead – we call this smash factor. With an older model, the ball might come off the face with a 1.35 smash factor.

However, strike the ground early and you will get grass and mud trapped between the ball and the face. This means that the COR of the clubface becomes less relevant, and the smash factor of both the old and the new club will drop down to something more similar.

In this regard, a newer club could potentially cause greater distance dispersion between a flushed shot and a slightly heavy shot – which could wash out any potential advantage gained from having a larger sweet spot.

Also, it is my experience that a player often creates more mistakes with ground contact than face contact.

Expectations/Psychology

On top of this, when a player says “I have picked up 2 clubs of distance”, it is much more likely that they have only picked up one.

Humans are known for embellishing, and we can even lie so well that we can fool ourselves. We will often compare our new clubs’ flushed shots to our old clubs’ average shots, creating a distorted view of how much distance we have actually gained.

This factor alone can wash out the forgiveness created by the modern clubs.

It is my experience that players with new clubs will also have a greater tendency to play a strategy based around their flushed shots more than their average shot, just because they want to prove to themselves how far these new babies will go.

Getting Lazy

A phenomenon I have also seen first hand in lessons is that, when you give a player a bigger headed / more forgiving club, their strike patterns start to spread out and become less consistent.

There could be a couple of reasons for this.

1. Because the club is so forgiving, the player can no longer feel when they miss the sweet spot by an inch – so their brain does not rectify the issue.
2. A bigger headed club tells our brain that we are free to make a larger mistake.

As an analogy for the second point, if we told a person to hammer a nail with a very small headed hammer, they would likely constrain the action and produce a tighter spread, even if they miss the nail more often. However, give them a nail and ask them to hammer it with a frying pan, they might make a wilder, less constrained motion. They might hit the nail more often, but the centre of gravity of the nail and frying pan would have a bigger dispersion.

It’s an interesting motor learning concept.

Improve Strike Quality

There are certainly course-management strategies that can make the above shot patterns perform/score better. While I would always recommend using improved strategy, we can also reduce distance dispersion through better strike quality.

By improving face contact and (specifically in this case) ground contact, we can reduce the distance between our flushed shots, average shots and slightly miss-hit shots. If you want to find out how to do this, check out The Strike Plan by clicking the link or the image below.

New Clubs ARE Better

This is an important point which I have waited to make until the end – because I want to clarify my message.

I am not saying new clubs wont make you better – far from it. Modern clubs are longer, straighter and have less of a drop off in distance on off-centre hits. More importantly, getting your clubs fit for you can be a huge benefit to you.

New clubs are also more fun – it is nice hitting the ball so far and having to be less precise with our face strike in order to do so.

However, due to

• Strategy
• No actual improvements in strike quality (new clubs just let you get away with more)
• Increased expectations of how far you are actually hitting the new clubs
• The “laziness” effect

You might not get as much benefit from that extra distance as you should be getting. Just something to think about.

Summary

Get new clubs – but make sure you still work on strike quality and strategy to maximize the effectiveness of those new toys.
