Everything you need to know about the Project X LZ iron shafts
When golfers think of iron shafts played on the PGA Tour, two models generally come to mind. The first is the most-used shaft on the PGA Tour, True Temper’s Dynamic Gold. It’s been the leading choice of serious golfers for nearly four decades. The second is another True Temper shaft. Called Project X, it has been around a little more than a decade, and is the second-most played shaft on the PGA Tour.
It’s starting to feel as though True Temper’s new Project X LZ iron shafts could be another classic in the making, with three high-profile wins in the last four months. Adam Scott used the shafts to win the Honda Classic and WGC-Cadillac Championship, while James Hahn won with the shafts the first week he used them at the Wells Fargo Championship.
What’s different about the Project X LZ shafts, and what can they do for your game? We asked Don Brown, True Temper’s Director of Golf Innovation.
WRX: What’s the difference between the Dynamic Gold, Project X and Project X LZ iron shafts?
DB: Dynamic Gold and Project X share very similar performance profiles. Both are low- launch, low-spin shafts that weigh roughly 125 to 135 grams and both have reinforced tip sections. While their launch conditions are very similar, their EI profiles and feel are very different. Dynamic Gold has a tip section that changes in length (distance to the first step) as you move through the set. Project X, on the other hand, has a 2-inch tip section on every shaft in the set. These differences create a much different feel for these two similarly preforming shafts.
Project X LZ is a different design all together. The PX LZ has both a reinforced tip and butt section, which creates a mid-section that is more active. This allows the shaft to load more and provides exceptional feel. This three-wall design is very unique to the steel golf shaft industry. The PX LZ also has a series of very small micro steps in the midsection to enhance the loading zone even further. It will provide a mid-launch angle with a flat apex.
WRX: How long was the Project X LZ shaft in development? What challenges were there in its design?
DB: As we were seeing the great results with our early prototypes of graphite Project X LZ in late 2013, we immediately began to think if we could see the same benefits in a steel shaft. The challenge was how to create that same affect in a steel shaft. There is a lot more freedom of design with a graphite shaft, where we can easily change the different layers of graphite, as well as use different grades of graphite. In steel, you need to be able to make changes to the internal reinforcement of the shaft and are working with a singular material.
Our steel engineers spent over a year manipulating the steel trying to create the Loading Zone signature EI profile. When they still hadn’t perfected it, they realized they were going to have to do something unconventional. All of our tour shafts have reinforced tip sections for added stability and trajectory control, but for the LZ signature, we were going to have to reinforce the tip and butt sections. That presented a lot of manufacturing challenges that took many months to get right. Finally, with the tri-walled designed dialed in, we added the series of micro steps to increase the flexibility in the loading zone even more. It took almost 2 years to get the designs dialed in, and a few more months of player testing, but with the rapid tour uptake and 3 PGA wins in a few months, it was definitely worth it.
WRX: What has been the feedback from tour players?
DB: Obviously, we have had great success on Tour already with several major champions putting the shafts in play, and over a dozen different players having added it to their bags.
A lot of the players who are adding it are looking to work and flight the ball a little more than they can with the traditional low-launch, low-spin products that dominate the Tour. I think we are seeing players being more receptive to new technologies like LZ and (True Temper’s Dynamic Gold) AMT, as opposed to sticking with traditional designs and weights.
WRX: How do PGA Tour players test new iron shafts? Are they more concerned with what their launch monitor says, what their ball flight does, or what they’re feeling during their swing?
DB: For irons we use the launch monitor, but the data doesn’t figure into decisions as much as it does with drivers. With a driver, the numbers are usually king, and a good range session with a driver shaft can be enough to switch. With irons, it’s more about feel and ball flight. Players aren’t worried as much about distance; they want to see a trajectory and ball flight that they like, and have a feel that gives them confidence.
If a player is satisfied with his current irons, it will usually take a couple rounds of testing before he will consider switching. A player who is searching might switch in the same week, but not without some on-course testing first.
WRX: Some tour players use the same shafts in their irons as they do in their wedges. Others use the same model, but one flex less in their wedges. A smaller group of tour players use completely different shafts, or those specifically design for wedges. Is the Project X LZ a good wedge shaft?
DB: With wedges, usually we see the pitching wedge is the same shaft as the set, and the other wedges can be independent. With our LZ players, we have some who have gone to LZ through the set, some who stuck with their existing wedges shafts and one player who is still testing LZ in his irons, but has put LZ into his gap and lob wedges.
LZ certainly can work well as a wedge shaft, but for many players wedges are about confidence and feel, so we don’t see players switch their gap, sand and lob wedges shafts very often.
WRX: Anything else we need to know, Don?
DB: I encourage all GolfWRX readers to give the LZ shafts a try at a demo day or club fitter. The technology in these shafts is really unique, and provides a different performance and feel than anything else out there on the market. PX LZ are available now from our PFC dealers, and many of the OEMs have already added them to custom or will be adding them very soon.
WRX: Thanks Don.

WITB Time Machine: Rory McIlroy’s winning WITB, 2014 PGA Championship
It’s hard to believe it’s been 10 years since Rory McIlroy outlasted Phil Mickelson at the 2014 PGA Championship. It’s even harder to believe McIlroy hasn’t hoisted a major trophy since his 2014 victory at Valhalla.
After a slow start to his final round, McIlroy tallied an eagle and two birdies on the back nine and his fourth major championship. Take a look at the clubs he played a decade ago in Kentucky.

I’ve been swinging the 2006 satin finish 6.0 Project x matched with the satin finish 2006 TP MB’s ..my game is a little funny right now but still around 69-72ish ..how would th PX lz compare to my 2006 PX ?

Some specs. would have been nice to include. So many factors go into picking the right iron shaft for your swing.
I have good swing speed but don’t load real aggressively so I start with that idea in mind when I look at any shaft . They are for the most part all good shafts just find the one that fits the best is what counts. I don’t really care what the guys on tour play because I don’t swing like them anyway.

Why are you posting this information now, when this shaft is over 2 years old?
Dave
May 20, 2016 at 5:09 pm
125to135 gram shafts ,you would have to have a pretty fast swing speed to hit these all day ,and be fairly muscle bound also . I know personally I would be tired after 12holes trying to swing these.

If you’ve ever swung a DG S300, one of the most popular/common shafts, you’ve swung a 130g shaft. It’s a pretty standard weight for steel shafts…with, of course, numerous lighter options available. You seem to think this is only for tour-level and/or burley players and its Titleist’s stock iron shaft. Lol. Even the R300 is 127g. Most people can load a shaft of that weight, it’s a matter of finding the right weight to lock in tempo and your personal preference of swing weight.

Personally, I like the idea, but my favorite shafts are KBS Tour C-Taper. I really want to try out Dynamic Gold AMT, but these look fantastic!

Well it sounds like Modus 120. I guess LZs are pretty nice as well. I’d rather have shafts made in Japan though – Nippon.

It sounds more like the profile of the Modus3 125 version.

May 19, 2016 at 2:02 pm
I think these seem like they are made to compete with the KBS Tours… sounds like a similar profile maybe the Modus3 as previously mentioned as well….

I would be really interested to see a testing against these and what, in my mind, sounds like a similar shaft weight/flex point like the Nippon modus3 125’s. Personally, these went in my irons this year and the trajectory and dispersion is phenomenal…but being a wrxer, naturally when I see something new and shiny I want to play with it.

I wonder how these would compare to my PXi shafts.
Lp
May 20, 2016 at 2:13 am
Not even the same. PXi is softer tipped. PX is stiff tipped.

When I think of iron shafts played on tour I also thing of KBS and Nippon as well. So just mentioning True Temper is bit far fetched. I understand it is in the context of the article but bit misleading – stop favouring specific brands. I play the PX and would be interested to try the LZ but certainly will also have KBS on my mind.

Considering the article is an interview advertorial piece, why mention the competition? Everyone reading already knows.

golfraven,
what in the heck on Earth are you blethering about? True Temper owns PX. So why wouldn’t any writer mention PX with True Temper? It’s the same company.
