Project X LZ Tour Graphite Iron Shaft Review

Project X LZ Graphite Iron Shaft Review

The Project X Loading Zone steel shaft is getting a lot of tour play. Our tester with a 117 mph driver speed has made the Project X LZ 6.5 his gamer in his irons. Now the same brand name is on a 90 gram carbon fiber shaft for those of us with more modest swing speeds. I first noticed the shaft when my 2017 Mizuno fitting cart update arrived. This year’s 90g shaft from Mizuno is the Project X Tour LZ in a 5.0 and 6.0 flex.

What really got my attention was the FlexLoc torsional bands in the mid section of the shaft. These are the same bands used in the Project X LZ driver shafts. In the driver shaft, these band maintain stable torque and hoop strength through a section of the shaft with reduced wall thickness that created the soft midsection loading zone.

Stay tuned, I will add some range testing shortly. I am very interested to see if this design busts the distance loss we face as the stiffness associated with aging reduces club speed.

    Maybe I don’t understand the chart and you could please explain. You show the tip and butt torque of the 6.0 shaft to be greater than the 5.0 shaft and the 6.0 shaft a hair lighter. I always thought as the shaft got stiffer it was usually heavier and had less torque?

    • Ah, you see what I see. You understand the chart. What you see is the minor quality control issues common in carbon fiber manufacturing.

        Thank you for your reply. If I understand correctly then, this is not intentional and it would be possible to find 5.0 shafts that had more torque than 6.0 shafts simply due to inconsistencies from shaft to shaft.
