The short answer — Simplicity (which leads to Consistency, Accuracy, Lower Scores, and More Fun).

Because you have a better chance of hitting your golf ball closer to your target.

Simplicity – By not having to worry about ball position or modifying your swing tempo, you have a much simpler swing.

Consistency – By repeating the exact same swing 20-25 times a round, you will begin to groove that single swing plane in no time.

Accuracy – As a direct result of your simpler, more consistent swing, your accuracy will steadily increase and your scores will drop.

All of the irons have one length, one weight, and one lie angle, which means that they also have one swing plane, one tempo, and one optimum ball position — it’s that simple.

Besides the length of the irons, the primary differences in the single length irons when comparing to traditional irons are the loft angles of the clubs, which tend to be a couple degrees stronger for each club.

Bryson DeChambeau is currently the first PGA Tour professional to exclusively use single length irons, and he is a brand ambassador for Cobra Golf, the first major golf manufacturer to offer single length irons.

Using single length irons in 2015, Bryson became just the fifth player to win the U.S. Amateur title and the NCAA championship in a single year, joining Jack Nicklaus, Phil Mickelson, Tiger Woods, and Ryan Moore.

In September 2016, Bryson won the DAP Championship (Web.com Tour Finals event) to earn his first professional victory and his 2016-2017 PGA Tour card.

Because we’re creatures of habit and we have hard heads!

And because it’s much easier for the golf retailers (Golf Galaxy, Dunham’s, etc.) to stock “standard” sets of golf clubs rather than 3 or 4 different lengths of each single length irons set. These golf retailers sell 85% of all golf clubs and are conveniently located in every metropolitan area of the country.

Luckily, in January 2017, Cobra became the first major manufacturer to launch single length iron sets.

Because we’re using the wrong tools — my dad always says “Use the right tool for the right job!”

We wouldn’t use a sledgehammer to tap in a simple nail — standard iron sets are the sledgehammer of the golf game — we should stop using them!

Professional golfers’ ability to pay their mortgage comes from being able to master the 10 swing planes necessary to use 10 different lengths of conventional golf club sets. They spend the bulk of their waking hours honing their golf game to the point where they can easily switch between different length clubs from one shot to the next.

A standard golf club set is the sledgehammer, which enables professional golfers to hit a 4 iron 250 yards into a long par-3.

The other 99% of us don’t need that sledgehammer, but rather, need the accuracy of using a claw hammer.

“I’ve hit fliers with the four. I’ve hooked my five, I shank my six, skulled the eight, fatted the nine, chili-dipped the wedge, and bladed the sand. But then there’s the seven iron. I never miss with the seven iron.” – Kevin Costner in Tin Cup

Because golf is not our profession — we don’t have time to learn 10 swing planes, 10 swing tempos and 10 ball positions. There is inevitably one swing plane that works for us better than all the rest.

Your optimum iron length is unique to you and is determined by your height, the distance from your wrist to the floor, and your optimum swing plane.

It is best to get professionally fit before you decide to purchase your first set of single length irons so that you don’t end up wasting time and money like I did (see my single length irons journey).

Because we love explaining why we spend so much money on golf when we get home.

Probably — and they’ll stop laughing as you stack up skin after skin.

Seriously though, I’ve had the opportunity to play with several random groups of people while using my single length iron set (my regular golfing partners have back issues). Not a single one of those people have negatively commented on my choice of irons.

In fact, several of them ask me what clubs I’m using by the third or fourth hole and are genuinely interested in hearing about my single length clubs and how I ended up choosing them.

Absolutely — many sets are already on the USGA list of conforming clubs.
