-Custom clubfitting system designed by Tom Wishon and Jaacob Bowden
-Single-length irons drastically simplify swing thoughts and reduce setup adjustments throughout the set.
-Simplifies the game and makes it more fun
-High quality product
-Good Gapping, trajectory, range
-More consistent impact (More on centre hits, less thin and fat shots)
-Identical feel from iron to iron
-Identical function from iron to iron enhancing length, distance and dispersion control
-Identical setup, swing, ball position, stance from iron to iron
-More Consistency will probably lead to improved scoring (many factors to consider; putting, driving, chipping etc.)
-It takes time to get used to the feel and appearance of longer short irons and shorter long irons
-To make the concept work requires custom club fitting (If you have an 8 iron that you play well with, contact Sterling Irons and they can help you through the rest of the process)
-Slower swinging players will require a hybrid for irons 5 and above (this is true for variable sets as well)
Bobby Jones, Bryson Dechambeau & Single Length Irons:
The concept of making each iron the same length in a set of golf clubs is not new. The idea goes back to at least the 1930s. Bobby Jones designed a set for Spalding in which every two clubs were the same length (3 and 4 iron were the same length, 5 and 6 iron, and so on). Most people know that Bobby Jones is the only golfer credited with a single-season Grand Slam, but did you know he did it with single length irons? He was the dominant player of the 1920s, and co-founded Augusta National Golf Club and The Masters. If the concept worked so well “why is each club a different length now?” After all, with a movement as complex as a golf swing; where club head inaccuracy of an inch or a couple of degrees makes a big difference in result, why complicate things unnecessarily? A few companies tried to bring back single length sets yet failed; but for what reason? Jack Nix of Albuquerque obtained a patent on the one-length concept in 1976. He later sold it to Tommy Armour Golf, which introduced a line of single-length irons in 1989. The EQL irons were built to 37” (today’s 7-iron length) and also had a matching set of woods built at 42”. They were the talk of the PGA Merchandise Show that year and sales were amazing. Unfortunately for them, the distances bunched between clubs, there were reported trajectory problems with the irons, and the driver went shorter distances for some people. The line bombed, and the concept never gained widespread appeal.
So why did the irons fail, maybe it was due to the lack of technology? On the other hand though, probably not because Bobby Jones had them in the 1930’s and he did pretty well. Had the game of golf changed so much that single length irons are not a viable option anymore? This answer does not seem likely either with the resurgence of single length irons thanks to Bryson Dechambeau’s wins on tour, proving the concept is still viable. It seems to me back in Bobby Jones’s era, golf clubs were custom made and fitted to each golfer like a custom tailored suit. Nowadays they are all mass produced to buy off the shelf with a one size fits all approach. That was the ‘aha’ moment. Bryson Dechambeau and Bobby jones had ultra custom fit clubs. Golf clubs that are made to fit their swing. The problem seemed obvious, the single length concept seems to exaggerate the problem of people not getting custom fit. There are 12 key club fitting variables that need to be fit to each golfer because golfers are different in size, strength, athletic ability and swing characteristics. Not many golfers will play their best when purchasing off the rack clubs with generic specs.
Club fitting technology is where people can find real game improvement in variable and single length sets. We scoured the web to find a company that custom fit single length irons to give me the best chance to make the concept work. We found Sterling single length irons which offers 4 different steel shafts, 10 graphite shaft, 2 different club length options, 7 lie angles, 12 swing weights, and 6 grip size options. They also have the veteran club fitting guru/wizard Tom Wishon at the helm. With more than 35 years of experience in the field, Tom Wishon is recognized as one of the industry leaders in the research of golf club design, performance and club fitting technology. We got in touch with Jaacob Bowden, the creator of Sterling Irons and he sent us a set. When they arrived we were pleasantly surprised how beautiful the irons were, the pictures on the site don’t do them justice.
The benefits behind the concept?
The concept of making every iron the same length is to simplify the game by letting the golfer use the same stance, posture, spine angle, ball position and swing plane. Eliminating these variables in theory should produce better swing repeatability and shot consistency.
First impression (Looks, Sound & Feel)
This stunning set of clubs is divided into two different types of irons – a conventional cast steel set (soft steel) in the 8-SW and a High COR design in the 4-7. Both iron designs have sleek contours, narrow top lines and soles for a good address position and a matte silver finish.
The 8-SW irons have a soft buttery, solid, consistent feel throughout whereas the 4-7 feel blazing hot off the face thanks to the High COR design. The High COR design also produces a distinct metallic ping sound at impact, which I don’t mind. Both sets were silky smooth and magical to hit.
How we tested?
We put the Sterling Irons to the test by performing 3 days of testing. Day one the tester hit the whole bag of irons to asses for gapping and range. Day two we compared the trajectory and dispersion of Sterling irons pw, 7 and 5 iron to a conventional set. Day three we put the irons against the conventional set again to asses consistency with impact tape. With our testing we wanted to find out two things. One, did Sterling fix the gapping, range and trajectory problems that plagued other companies? Two, by assessing dispersion and impact did the Sterling Irons produce better swing repeatability and shot consistency than the testers conventional set?
- Sterling single length irons were used for this test. The golfers hit a custom set of clubs that were fit for him based on the Sterling website and expertise by the company.
- Lie angles, grip size, swing weight, shaft flex and length, of the Sterling set were adjusted to golfer’s equivalents.
- All testing was conducted inside our test facility located in Winnipeg, Canada. All ball data was collected using our trusty SkyTrak launch monitor.
- Tester is a 34 year old, mid swing speed golfer, average ball striker, Handicap: 17-18.
- Plays on average 20 rounds per year and competes in club-level team events, not in individual tournaments.
- Current set: 2011 TaylorMade MB Forged PW-7 Iron, 6 Iron- 4 Iron MC.
- We usually have numerous testers but because this concept requires each tester to be custom fitted to get unbiased results, we had one tester. If we had numerous testers try the same clubs we could not be confident that fitting didn’t play a role in the results.
Did Sterling Irons solve the gapping problems that plagued other companies?
“Golfers need a spread — a pattern — of distances that various clubs will travel. When a custom clubfitter bends the lofts to create that pattern, the process is called “gapping”; it generates a set of yardage gaps from each club to the next.”http://tutelman.com/golf/clubs/singleLength1.php
There were reports with other single length iron manufacturers of their low-lofted irons flying too low and short, and high-lofted irons flying too high and far. Furthermore, it was also common to see distance gap bunching problems. It’s when you have 2 clubs that go similar distances and essentially in that case are the same club. This becomes a problem because you need every club to travel a different distance so you can hit various targets on the course. There is no correct golf club distance, there is only your distance. The average yardages for each golf club depends, and it varies widely from golfer to golfer. One person’s 5-iron distance is another person’s 3-iron distance is another person’s 7-iron distance. Knowing your distances is more important than knowing how far each club is “supposed” to go. Most golfers get 10-15 yards overall difference between clubs but for slower swing speeds it could be between 7-9 yards difference between clubs. We found the gapping in the Sterling set to mostly be in the area of 12-19 yards. With an exception between the 8 and 7 iron, which was 8 yards; and between the 7 and 6 iron which was 9 yards. Overall, we found the gapping to be good. However, if issues arise, as previously mentioned above in the quote, bending the lofts would help adjust the gapping in the above mentioned clubs to above 10 yards.
|Club||Total (YD)||Gap (YD)|
Did Sterling Irons solve the range problems?
“The range of a set of clubs is the difference in distance between the longest-hitting and shortest-hitting clubs. It’s the range of yardages you can cover with a full swing. And, unless you mess around with loft lineup and other features, you will get more range from conventional irons than single-length irons. We’ll see it quantitatively below, but let’s just state the general reason first. The difference in distance from club to club is based on two important variables: loft and clubhead speed. Lower loft gives greater distance. Higher clubhead speed gives greater distance. And, for a properly-designed and -built set of irons, a longer club delivers greater head speed.”http://tutelman.com/golf/clubs/singleLength1.php
Looking at the research that has been done, comparing single length irons to conventional length irons there will always be a range difference between the sets. For example, the Tutelman study found a minor range difference between the two sets of less than 10 yards out of a 100 yard range. We did not do a study comparing the ranges because we know there will be a difference. This problem can be simply fixed by adding another club to increase the range in a single length set.
Did Sterling Irons solve the trajectory problems?
In our study we found that the PW trajectory was higher and the 7 and 5 iron trajectories were lower than the conventional set. There is a difference in trajectories between sets but this should not be a problem since the gapping and range work well. The only caveat is based on course conditions. For example, in windy conditions, lower trajectories work best as it is less effected by the wind but it tends to roll more therefore can be problematic on fast greens. Compared to higher trajectories, which would be better for fast greens but tend to be effected by windy conditions. My point is if you change to a single length set, you might have to change your course strategy.
|Club PW||Launch DEG||Height YD|

|Variable set (Green)||27.5||26|
|Sterling iron (Pink)||21.6||25|
|Result||Sterling -5.9||Sterling -1|
|Club 5 Iron||Launch DEG||Height YD|
|Variable set (Blue)||19.4||27|
|Sterling iron (White)||18.5||25|

Did the Sterling Irons produce better swing repeatability and shot consistency than a conventional set?
Our study found overall that the Sterling Irons produced better swing repeatability and shot consistency than the conventional set. The results showed that the Sterling Irons had a tighter dispersion, and just as good or better impact consistency.
(Note: Impact tape was used to test the PW, 7 iron and 5 iron for impact consistency.)
|Club PW||Dispersion YD|
|Variable set (Orange)||45.4/47.6|
|Sterling Iron (Yellow)||44.0/57.7|
|Result||Sterling was more accurate in carry dispersion |
but was slightly less accurate in roll dispersion
|Club 7 Iron||Dispersion YD|
|Variable set (Green)||52.1/60.7|
|Sterling Iron (Pink)||51.2/50.2|
|Result||Sterling Irons dispersion was more accurate|
|Club 5 Iron||Dispersion YD|
|Variable set (Blue)||39.0/57.9|
|Sterling Iron (White)||36.5/39.0|
|Result||Sterling Irons dispersion was more accurate|
When assessing reviews, we try to see the big picture; did majority like or dislike the product? If there is no big consensus, read the ratings situated in the middle. In my experience they seem to provide constructive criticism. This one was easy to asses because there are many Sterling iron reviews and 99% were positive.
Sterling Irons Testimonials page
Our testing revealed that the Sterling irons fixed the gapping and trajectory problems that plagued others and provided better swing repeatability and shot consistency than a conventional set. Our tester said it felt like cheating hitting a bag of 8 irons. Basically the clubs passed with flying colours on all accounts! We recommend however, to optimize the concept for single length irons you should get custom fitted. Club fitting technology is where people can find real game improvement in variable and single length sets (note: If you have an 8 iron that you play well with, contact Sterling Irons and they can help you through the rest of the process). The single length concept simplifies the game and makes it much more fun. This is great because it breaks down more barriers for people wanting to play golf. There were many customer reviews and 99% are positive, it wasn’t just the usual marketing hype it was based on real golfers who tried the product. The single length concept is here to stay and will probably take over the scene and diminish the amount of people using conventional sets. I included some quotes below that hits this point home.
“I’ve heard from a multiple major-championship winner that in five to eight years you’ll see a quarter of the players on tour playing single length,”
“You know that if your swing is on with your 7-iron it’s going to be on with every other club, and you also know that if there’s a swing flaw with your 4-iron, you can fix that and you’ve fixed it for your whole bag.” -Skaggs
“Believe it or not, if I had to do it all over again as a 13 or 14-year-old, I would go to one-length clubs,” Norman said. “I actually had a set made for me when [Bryson DeChambeau] first came and joined, and I got it straight off the bat. When you think about it, my 4-iron and my 8-iron are the same length, but my ball flight was so good on all of them because your spine angle stays the same.” -Greg Norman
“I think parents now, for longevity, golf is a sport you can play your entire life, so if you look at that motion that [DeChambeau is] going through there, it’s such an effortless motion. He’s stacked up beautifully. At the end of the day, the motion is so simple through there. So the one-length golf club, in my humble opinion, give a kid at six, seven, eight…get him used to it and he’ll do well.” -Greg Norman
