Driver Golf Shaft – Matrix VLCT SP & Matrix VLCT ST

The VLCT model is the 2014 driver shaft from Matrix Golf Shafts. It is available in two versions, Sp and St. The stiffness on the shaft is shown as a speed rating. A = +75, R = +85, S = +95 and X = +105. My review samples were the original graphic. The name on the shaft is VELOX, that is changing. If you see a shaft labeled Matrix Velox, it is the same shaft, different graphics. The ST version has a stiffer tip to promote a lower launch.
Matrix uses the term CFI, Circumferential Flexural Integrity for what I call radial consistency. They define it perfectly as ” an innovative layup method devised to insure a shaft’s flexing properties are consistent around the 360 degree circumference”. I checked a total of 18 shafts and found the radial consistency at 99.0% with a 0.7% standard deviation. Those numbers translate into a shaft that can be installed in any orientation. The shaft is suitable for rotating hosels. Alignment will add nothing of value to the performance of the Matrix VLCT shafts.

The Velox 60 gram ST shaft is stock in the 2014 TaylorMade JetSpeed TP driver. At $400 retail for the driver, that is a great bargain, considering the retail price of the shaft alone is $375.
