Sterling Single Length Irons

It’s easy to overthink a problem, but sometimes the simplest answer is also the most effective. So, if you struggle to hit your irons consistently, you could take lessons, read instructional books from the who’s who of teachers, practice more, try a couple of different brands, or, you could remove a bunch of variables and play them all at the same length.

Get Ready For The Consistently Lowest Scores Of Your Life!

A huge reason golf can be so difficult and frustrating to play on a consistent level is that all your irons are different lengths, have different club head lie angles and different ball positions. This forces you to have to learn 8 completely different swings just to use all those irons for approach shots.

But, what if it didn’t have to be that way? What if you only had to learn one swing and it was the only perfect swing that’s biomechanically correct for your body?

Single Length Irons - History

Late in 2013, Golf Professional , Jaacob Bowden went to visit Tom Wishon, a 40-year veteran of the golf equipment industry specializing in club head design, shaft performance analysis, and club fitting research and development.

Jaacob asked Tom if they could co-develop a cool-looking single length iron design that would retain all the inherent benefits of single length sets while solving all the problems.

After 2 years and 6 months of research, human and robot testing, and development, the result of their hard work is Sterling Irons®.

Sterling Single Length Irons

Sterling Irons® are the world’s most technologically advanced set of single length irons the world has ever seen.

They are inherently easier to play. One single length iron means one single swing for each club. You end up gaining a ton of consistency, hitting the ball closer to the target, and shooting lower scores.

Greg Norman's Thoughts On Single Length Irons

Greg Norman hosted the 30th annual QBE Shootout in Naples, Fla. during December 2018 and talked about Single Length Irons with Golfweek magazine.  Here is what he said:

      • “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 (DeChambeau) first came and joined Cobra Puma 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.”

If Greg Norman can realize the benefits playing with them, then you could too.  Actually, it's quite likely that you will experience comparatively more benefits than Greg Norman did!

Review by Paul Wilson - PGA Professional - Director of Instruction - Bear's Best Las Vegas

Paul's Conclusion:

"After finally hitting a top quality set of single length irons, I can honestly say I was impressed with not only the look but the feel as well. If you're in the market for single length iron's then I highly recommend Sterling Irons. It will take you a little while to get used to them because they are different but once you do, you will never go back."

Single Length - Philosophy

Designing a set of single length irons is an engineering exercise that requires resolving the numerous and varied issues associated with making the concept work. On paper, the positives are overwhelming. When every club is built to the same length (most built at a 7 or 8 iron length), the golfer needs only one setup, one ball position and only one swing for every club. In theory, this should make it easier for a player to make consistent contact.

Paper and reality don’t always align perfectly.

Because every club is the length of a typical 7 or 8 iron – the single length long irons (3, 4,5) are comparatively shorter than their variable length counterparts. while the short irons (9, PW, GW, SW) are longer. Using standard head weights, the pitching wedge would swing like a sledgehammer, and the 3 iron would feel like the driver from your kid’s junior set. And that’s before we even consider ball flight.

To get consistent yardage gaps between irons, every facet of the club needs to be considered and tweaked to optimize performance.


Single Length Irons - Problems

There are a variety of historic problems within the single length market. Some of the primary issues were that not all the manufacturers had USGA-conforming grooves, there were limited custom fitting options, distance gaps sometimes bunched, and there were trajectory problems with all the manufacturers in that the low-lofted clubs flew too low and high-lofted clubs flew too high.

I would like to cite Kirk Oguri, a Golf Digest Top 100 Clubfitter with extensive single-length fitting experience.  Both he and I, feel players are best served by relying on CG (center of gravity) location and COR to manipulate flight and distance. That’s where Wishon hit's the mark and other OEM manufacturer's miss.

Sterling Single Length Irons - Solutions

The goal for Bowden and Wishon was to create a functional set of irons which leveraged the benefits of single length, and “looked cool.”

Sterling relies on changes in COR and offset to produce optimal flight in longer irons.  Specifically, the 5-7 irons use thinner-faced HS 300 steel to boost ball speeds. The top end of the set is cast from 8620 carbon steel. Wishon cautions against companies like Cobra who use 17-4 stainless to create hi-COR heads. Wishon believes the material isn’t strong enough to support faces thin enough to generate the ball speed necessary to overcome the distance challenges associated with single length long irons.

To protect against too low launch and spin, Wishon increased offset in the long irons to move the COG farther back, which helps players launch the ball higher and farther.



The Sterling Approach

Another distinction in the Sterling approach is that the set is built to standard 8 iron length, not 7 iron like Edel and Cobra. While each set can be altered to the player’s preferred specs, starting with a shorter club in Wishon’s experience, makes the adjustment to longer short irons easier.  It makes the entire set easier to hit in general.

Admittedly, the Sterling irons are targeted at the middle 75% of golfers, most of whom struggle hitting their irons consistently and don’t have the swing speed to create optimal launch conditions with anything with less loft than a 6 iron.  However, ALL levels of golfers can take advantage of the consistency and forgiveness benefits playing Sterling SL irons.

Wishon is convinced there’s a real benefit in single length, not only for golfers who have never been able to find a repeatable iron swing or are just taking up the game, but for any golfer.

Proven Success with Single Length Concept

The current golf market is more receptive to the Single Length concept.  In part, it is due to the recent success of Bryson DeChambeau.  He used a set of single length irons on his way to becoming the 5th player in history to win both an individual NCAA championship and US Amateur Championship in the same year. After turning pro in the spring of 2016, DeChambeau has used single length irons to capture professional victories on the, PGA and European Tour’s.  In the early part of 2019, he has climbed to the 6th ranked player in the world.  He credits much of his success to the single length concept.

Engineered Golf's confidence in single length irons is also partially rooted with Bryson DeChambeau's success.  He's won at the highest levels of amateur and professional golf.  It’s understandable why we see this technology as offering tangible benefit for a wide-range of players.  I personally see the benefits from playing Sterling Single Length irons.


Custom Fitting

Wishon has long been a vocal proponent of custom club fitting and has authored a variety of books and columns on that topic. Even so, Wishon particularly emphasizes the importance of working with a fitter who can fit single length and understands the compensations necessary to optimize performance.

More than a conventional set of irons, single-length requires an expert fitter. Engineered Golf feels the term tailor is more appropriate than fitting. Anyone can get fit for a suit at Men’s Warehouse.  However, a truly great experience comes at the hands of a skilled tailor.  The skilled tailor not only understands all of the possible variables, but can arrange them in a way which measurably gives you the very best product.  We can do that for you.
