Project X LZ Iron Shaft Review

Let me break down what True Temper means by "Loading Zone Technology" because it's not just marketing fluff. The shaft has three distinct sections with different wall thicknesses, reinforced at the tip and butt, with a noticeably softer midsection. You can actually see the engineering when you look closely at the shaft. There are these rapid tapered steps from the grip down through the midsection, then micro steps that create what they call the loading zone. The micro steps in the midsection are a key part of True Temper's design approach to enhance loading characteristics.

What this translates to in the course is a sensation I've never experienced in a steel shaft. During the downswing, you can literally feel the shaft loading up energy in that midsection. It's not loose or whippy, it's controlled flex that releases right at impact. True Temper claims this design produces 7% greater energy transfer to the ball, and while I can't verify that exact number, I can tell you my ball speed increased by about 2-3 mph compared to my Versatile Golds with the same head.

The most surprising part? This doesn't feel like a graphite shaft trying to be steel or vice versa. It's its own thing entirely. The three-wall design (which True Temper says is unique in the steel shaft industry) creates this active feel without sacrificing the feedback you expect from steel. When you pure one, you know it. When you catch it slightly toward the toe, you feel that too. But unlike traditional steel shafts that can feel harsh on mishits, the LZ dampens that jarring sensation without masking what happened.

I tested the 6.0 flex at 120 grams, which is right in my wheelhouse coming from Versatile Gold S300s. The progressive weight system runs from 110g in the 5.0 up to 125g in the 6.5, so there's a good range for different swing speeds. The weight felt familiar, but the loading sensation was completely new.

Here's where the Project X LZ surprised me most. Every shaft I've tested that promised "mid-launch" either launched too high for my liking or started mid and ballooned. The LZ maintains what I'd call a true mid path with a remarkably flat apex. My 7-iron, which typically launches around 16-17 degrees with Versatile Gold, was coming out at 17-18 degrees with the LZ but with less peak height and more forward carry.

The spin characteristics are interesting, too. True Temper markets these as low-spin, but I'd say they're more "optimized spin" than purely low. My testing showed spin rates about 200-300 RPM lower than Versatile Gold but 400-500 RPM higher than the standard Project X. That's actually perfect for my swing, enough spin to hold greens but not so much that I'm losing distance in the wind.

What really stood out during on-course testing was the consistency of the flight. Whether I was hitting a stock 7-iron or trying to flight one down, the shaft responded predictably. The flat apex means wind has less effect on the ball, which became apparent during a particularly blustery round at my home course. Shots that would normally get knocked down were holding their line better.

The dispersion improvement was subtle but noticeable. Over five range sessions tracking with my launch monitor, my average offline dispersion with the 7-iron decreased by about 8%. Not massive, but when you're trying to hit specific quadrants of greens, every bit helps. The left-right consistency seemed particularly improved, which I attribute to the stable tip section maintaining face control through impact.

I've always been a "feel" player, and honestly, that's why I stuck with Versatile Gold for so long. They feel solid, stable, and predictable. The Project X LZ managed to keep those qualities while adding something I didn't know I was missing: smoothness. It's the difference between driving a sports car with a racing suspension versus one with responsive dampers. You still feel connected to the road, but the harsh edges are gone.

The "kick" through impact is noticeable but not distracting. It reminds me of the initial time I hit a well-fitted graphite shaft, that sense of the shaft doing work for you rather than just being along for the ride. But unlike graphite, the LZ maintains that dense, solid feel through the ball that better players expect from steel.

Temperature didn't seem to affect the feel as much as traditional steel, either. Playing in 45-degree weather in late fall, the shafts didn't feel as boardy as my Versatile Golds typically do in cold conditions. The active midsection seems to maintain its characteristics across a wider temperature range.

Even my regular playing partners noticed the difference in sound at impact. There's a slightly more muted "crack" compared to standard steel shafts – not dead, just polished. One buddy described it as "expensive sounding," which I think captures it well. It's the kind of subtle difference that makes you enjoy practicing more because every shot feels a bit more polished.

True Temper positions these as having a "broader player profile" than standard Project X, and after extensive testing, I agree with that assessment. The original Project X is aggressive, low launch, low spin, demanding of perfect tempo. The LZ takes that DNA and makes it more accessible without dumbing it down.

Players with faster tempos will particularly love these shafts. The loading zone doesn't require you to pause or slow down to activate it. In fact, I found that my naturally quick shift actually helped me enhance the energy transfer. This is different from some "active" shafts that need a smoother tempo to work properly.

If you're someone who's been playing Versatile Gold but wants a bit more help getting the ball airborne without going to a lightweight option, the LZ should be on your radar. That slight bump in launch with controlled spin is exactly what many players in the 5-15 handicap range need. You're not giving up control or feeling; you're just getting a bit more efficiency.

The progressive flex system (5.0 through 6.5) means there's probably a good fit regardless of your swing speed. During testing, I also tried the 5.5 flex, and while it launched higher than I prefer, the stability was still there. This isn't a shaft that gets whippy when you go down in flex; it just loads a bit easier.

After living with these shafts for two months, some benefits emerged that weren't immediately obvious. Initially, my arms and elbows felt less beat up after range sessions. That softer midsection really does absorb shock better than traditional steel. I'm 48 years old, and while I'm not ready to admit I need "senior" equipment, anything that reduces wear and tear on my body is welcome.

Secondly, the consistency in partial shots improved dramatically. Those 80% swings with a 7-iron, the knockdown 6-irons, shots where you're manipulating speed and path, became more predictable. The shaft's loading characteristics scale down nicely when you're not going full bore.

Third, and this might sound strange, but these shafts made me more confident with the ball. Knowing that the shaft was going to help me generate speed and launch without requiring perfect execution took pressure off my swing. I found myself making more committed swings, especially on approach shots where I might have previously tried to guide the ball.

The durability has been excellent so far. No signs of wear at the tip where the shaft meets the hosel, no paint chipping, and the steps in the shaft still look crisp. True Temper's reputation for build quality continues here.

Absolutely, while the Project X LZ Iron Shaft is a great product, there are a few pros and cons that you need to be aware of:

Pros:

• Exceptional feel that eliminates harshness without sacrificing feedback

• True mid-launch with controlled spin that doesn't balloon

• Noticeable energy transfer improvement leading to increased ball speed

Cons: 

• Price premium over standard Versatile Gold (about $15-20 more per shaft)

• Limited availability in some regions and custom builders

• May feel too active for players who prefer boardy, rigid feedback
