Project X Loading Zone Iron Shafts

Project X LZ Iron Shaft Review

I_PXLZ_ImageTrue Temper introduced the term “Loading Zone” with the Project X Loading Zone driver shaft a few years ago. I was skeptical at first, having seen other shafts with severe approaches to mid shaft stiffness that did not work for many of my clients. I put a Project X Loading Zone shaft in my own driver and it stayed there for several months. It comes back when I finish play testing a new design. It loads effortlessly and gives my unfixable negative angle of attack the launch I need to buy some distance. I was anxious to see how this approach would be implemented in an iron shaft.

The Project X Loading Zone irons shaft has a rapid loss of stiffness in the mid zone of the shaft. It then runs out in a long stable tip. We have seen some very successful implementations of this design over the last few years. Each with its own particular flavor. But overall in my fitting experience a very playable shaft for a wide range of golfers. This design is easy to load, creates a moderately higher flight but remains workable for the highly skilled golfer. I have seen this design add distance without adding dispersion. As of this writing, the Project X LZ has won 3 PGA events and is being played by close to 20 players between the PGA and Web tours.

Our player/coach/fitter partner has put these into his gamers for several weeks now. He replaced his Dynamic Gold Tour X100’s with the Project X LZ 6.5. His driver swing speed averages 117. He reports that he loves the feel of the shaft through impact. He gets a little lower flight and a lot more control. His ability to work the ball is improved. His dispersion is tighter. He reports he can trust the shaft to deliver the head consistently to shape his ball flight.

    How did the play testing go?

    Any updates on this shaft??? Thanks.

    • The players using it are not giving them back. They became their gamers.

      Thanks. A great shaft. Had a successful experiment with Taylormade PSI Tour heads and the Project LZ 6.5 shaft as mentioned above.

    So its a knockoff Modus3 120. Any feedback on if some guys like this even more than the Modus? I know you’re not into comparing shafts from one OEM to another but I thought maybe you’d take a shot at comparing these two.

    Also, can you speak to the genesis of this style shaft. Seems like Nippon was the first to experiment with it in iron shafts? Grafalloy seems to be one of the first onto the soft mid with the shaft Bubba plays to this day. Are those the pioneers or were there any earlier models that looked like this? Many thanks Russ.

    “So its a knockoff Modus3 120″…

    It’s kind of perfect that this was the latest comment in this thread, as I came here to comment on how much these two shafts, with what appear to be roughly similar EI profiles, differ from one another (in my personal experience). A well-respected builder recently recommended the Modus 120X in order to lower my launch and spin. He built up a 6-iron for me to try. I expected great things, given the love that this shaft has gotten. But I immediately hated it. The overall shaft felt too light/flimsy and the reinforced tip felt sort of like a ping pong paddle (light but boardy), with the ball quickly clicking off the face at impact. No sense of compression.

    Fast forward to the Project X LZ 6.5. I am absolutely in love! During fitting, from a feel perspective, I was always leaning towards an S/S+ flex, because I like to feel the shaft really load and kick. But I really need an X-flex to reign in my launch and spin. The Project X LZ solves this problem beautifully — reducing launch angle and spin rate while providing great loading sensation and excellent workability.

    Just goes to show you…even scientific measures like EI profiles are just a starting point in figuring out what shaft will perform/feel best for you.

      Great feedback. I have kind of settled into PX 6.0s. Played 6.5 a little but like you I just like a little more interaction with the shaft deflecting during my swing. Also tried Modus 120s and while I didn’t have the negative feel effects you got they launched a bit high and just weren’t quite as good as PX for my strike consistency. That said I might give the LZs a go and see if they’re even better. Have you played regular PX in the past, how do you compare them to LZ?
