Project X Loading Zone Driver Shafts

The Project X LZ, or loading zone shaft features a linear soft zone in the middle of the shaft which is visibly reinforced with bias wraps to maintain torsional stability. This 2014 composite driver shaft from True Temper, released under the Project X brand, is made in limited numbers in the USA facility in San Diego California. I am told only 60 or 70 can be made in any given day with current staffing.
This is an interesting option now being offered by a few companies. The general golfing public has access to the shafts that are made in the tour department for the tour players. Most graphite shafts are hand rolled. As such, the care taken by the person putting the shaft together is reflected in the quality and consistency of the finished shaft. Almost every company has some highly skilled wrappers that make their prototypes. And very often, when these people are not making protos, they are making the shafts that go to the professional tour vans. These shafts are not necessarily better than the shafts made in the volume production shops, but they are free of the shaft to shaft inconsistencies found in the factory produced product. And I have seen some inconsistencies that are hard to believe from the high volume, low cost foundries, but that is another story.
The concept of the Load Zone was to create a soft midsection in the shaft. Mid soft shafts are among the most popular shaft in my fitting experience. No shaft company likes to hear a section of their shafts being discussed as soft. If you make the tip stiff and the butt stiff, the mid is soft in relation to those other two zones. In the Project X Loading Zone shaft, the soft mid section is reinforced by a material called flex lock. That is graphite fiber oriented on an angle from the length of the shaft, commonly refereed to as bias or hoop plies. This stabilizes the torque in this zone. A full discussion of the design is shown in the videoed discussion I had with Don Brown, the True Temper graphite shaft product development manager.
