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.
