Project X LZ Tour Graphite Iron Shaft Review

Project X LZ Tour 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.
