The Mitsubishi Diamana GT is one of the 5th generation Diamana models. Mitsubishi Chemical Group is unique among the golf shaft companies, they are vertically integrated. They make all of the critical raw materials that make up the golf shaft including the monomer, acrylic fiber, carbon fiber, resin, and prepreg. Prepreg is the sheets wrapped around mandrels that are the material of the carbon fiber golf shaft. Other golf shaft manufacturers purchase the prepreg used in their shafts. This allows the Mitsubishi Chemical Group to create unique technologies in their golf shaft designs.
Once again, Mitsubishi has reduced resin content in the 5th generation Diamana with a proprietary resin system named Xlink Tech.

The Mitsubishi MMT Model Golf Shaft is available for Hybrid, Iron, Wedge and Putter. This review will focus on the hybrid shafts. We have seen carbon fiber shafts with outer wraps of stainless steel wire, here we have a shaft with an inner wrap. The Metal mesh technology is only in the tip of the shaft. This is not the first time Mitsubishi has integrated metal into their shaft prepreg. I have fond memories of the TINI wire used in the KuroKage shafts. Mitsubishi tells us the metal mesh added weight without having to add material which would have change the balance of the shafts. And like the TINI wire, the mesh adds a responsive straighten to the shaft.
