True Temper’s Area 61: R&D and Project PXi
Golf equipment companies go to lengths to manufacture the most cutting edge golf equipment designs, and they work equally as hard at marketing their products and facilities under names that describe their efforts.
Throughout the years, some names have been better than others. We loved names like “Futura,” “Anser,” and “Big Bertha.” Others like “Kombi,” “Redwood” and “Diablo” didn’t quite hit the mark.
Golfers might roll their eyes when they hear that golf shaft manufacturer True Temper named its research and development center Area 61 (Hey, are we chasing aliens are birdies?). But at Area 61, the True Temper team has been working hard to create extraterrestrial-performing golf shafts with very foreign characteristics.
One of these shafts, the PXi iron shaft, goes against the grain of what golfers have used for decades. At around 102 grams after trimming, it’s a lightweight iron shaft that mimics the characteristics of one of the most legendary heavyweight iron shafts in golf’s history, the Project X.

The PXi was the offspring of a True Temper iron shaft design called the Monaco, which Darren Clarke used to win the 2011 British Open. Monaco shafts were engineered with specific geometry for each iron, meaning the 3-iron shaft was created differently than the 4-iron shaft, etc. Yet all the shafts retained a constant weight because of True Temper’s VWT (Variable Wall Thickness) technology.
Greg Cavill, who leads design for True Temper’s iron shafts, said the Monaco was never meant for retail. It was initially a research project, and because of its extremely high cost to manufacture, it is no longer offered by True Temper. But its influence lives on through PXi.
Cavill and his team learned from Monaco that special geometry is not just important for each different iron shaft, but for each individual flex as well. While the PXi does not have variable geometry in each iron shaft like the Monaco, it has VWT in each different shaft flex.
[quote_box_center]“Why should high-handicap players use the same geometry as the players on Tour,” Cavill said.[/quote_box_center]
Even though the PXi 5.0 flex and 7.0 flex carry the same name, they have unique geometric construction that tailors to the different ways that golfers with different swing speeds load and unload the golf club.
The stiffer PXi shafts are designed with thicker walls in the tip section of the grip, which allows the butt end of the grip to take over during the downswing. This creates lower launch and lower spin results, while allowing the shaft to retain its lighter weight. The less stiff PXi shafts have a shorter and stubbier midsection and thinner walls in the tip section, which helps golfers with slower tempos and less abrupt transitions achieve their desired ball flight.
The PXi’s success has been proven by its place in the bags of two of golf’s best players, Rory McIlroy and Tiger Woods. Another major champion, Y.E. Yang, and two-time PGA Tour winner Jason Dufner have also been spotted with the PXi.
The reason for PXi’s success, according to Cavill, is that the shaft has allowed the best players in the world to achieve more distance, and even go to a longer club length because of the PXi’s lighter weight. For some of these high-swing players, they have also found a smoother, more stable feel because of the fact that most of the shaft’s work is done in the butt section of the grip. Watch the video below for more information on the PXi shaft from Chad Hall, director of True Temper global tour operations.

Did you catch the portion at the end of the video where Hall talks about the aesthetic value of PXi? According to Cavill, the finish of a golf shaft is the company’s next step in shaft technology.
[quote_box_center]“I can’t talk about it very much right now, but we’re working on a shaft that uses the technology of a shaft’s finish to enhance performance,” Cavill said.[/quote_box_center]

Slab city on the Korn Ferry Tour — Lead Tape Report
This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.





Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

Name every set of irons you’ve owned – GolfWRXers discuss
In our forums, one user has offered up a prompt for the true sickos, inviting fellow forum members to share every set of irons they’ve ever owned. As to be expected, this is a lengthy forum topic.
@Lamosteve began:
Can you name every set of irons you’ve owned? Here’s mine
Spalding Dots
Spalding Eclipse
Ram Lazer FX
Lynx Parallax
Mizuno EZ Comp
Ben Hogans
Cleveland CG Red

Our members in the forum have been offering up their own collections. Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.
- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”
- JimmyC59: “MacGregor Jack Nicklaus Triple Crown. Palmer The Standard. Still play these.”

Zak, Do you know whether there is any material difference between this year’s PXi shaft and the pre-PXi graphite iron shaft from last year?
