Bubba Watson plays the Grafalloy BiMatrix driver shaft and won the 2012 Masters with it. When he came on tour he showed up with one painted pink. Grafalloy accommodated him and made them in pink. For those that are not ready to play with a pink driver shaft it is also available in baby blue.

This design was introduced about 10 years ago and I tried it at the time. It was black back then and I still have an original R in the shop. I profiled it a few years ago and was surprised at the profile. It looked like a high launch design. The R flex profile from the original looks like the X flex I just profiled for this review. The current R & S flex have been redesigned for the typical R or S player.

Project X PXi Golf Shaft Review

Project X PXi Iron Shaft from True Temper

ProjectX_PXi_imageTT_PXvsPXi_EiIron shafts are getting lighter. Lighter means faster, it means more maneuverable. Think of the difference between a Carbon Fiber Lamborghini and a Heavy Metal Chevy. The light weight Lamborghini accelerates quicker, there is less weight to get moving. It corners quicker because it has less centrifugal force acting on it. The Project X PXi is a lighter faster Project X. The 6.0 model lost 12 grams of weight and 2 pounds of butt stiffness. Does it work? Ask Jason Dufner and Ian Poulter, they are both using it. And we have Tiger and Rory using it in their utility/driving irons.

Loss of weight typically means loss of stiffness. As you can see, the average stiffness profile of the PXi is softer than the average stiffness of the Project X. Once again, we see stiffness numbers on a shaft that do not indicate an absolute reference. Do not take that comment as a criticism of True Temper. It is the same scheme used by every shaft company. That is one of the many reasons that club fitting is so critically important to game development.
