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.

Nippon 123 Driver Fitting System Review

Nippon 123 Driver Fitting System Review

Most reviews here are focused on a single shaft model. The Nippon 123 system is three shafts brought to market as a fitting system. There are three profiles, each with an array of stiffness and weight. This is a fitting system that will soon be accompanied by documentation to guide the fitter using it. Mark Pekarek has been fitting over 35 years. Much of that time his company, Shaftology has been the distributor for Nippon shafts in the US. When I started with Nippon, Shaftology was the only source for Nippon shafts in America. Their distributors were regionally placed and had to demonstrate their golf competence as representative of the Nippon brand. Before you look at the data I recommend you watch this video shot at the 2019 PGA Merchandise show where the system was announced to the golf business.

This is the first time, to my knowledge, that a set of shafts has been designed and presented as a fitting system. Those of us with ample fitting experience have put together our own mix of fitting shafts. It takes years of experience and access to a comprehensive database of shaft properties to outfit a fitting cart for systematic fitting. As Mark said, the profiles in this system are different enough to make a difference to the average golfer.

Mitsubishi Tensei Pro Red Golf Shaft Review

Mitsubishi Tensei Pro Red Golf Shaft Review

The last profile added to the Mitsubishi Chemical Tensei Pro family of driver shafts is the Tensei Pro Red. Like the other Tensei Pro driver shafts it has a carbon Fiber Kevlar woven material place just below the hands. As you can see in the chart, this material substantially  increases hoop strength in this area of the shaft. Hoop deformation in carbon fiber golf shafts is a function of wall thickness. The wall thickness in the butt end of a golf shaft is thin. Therefore the shaft deforms more. This has classical be called ovaling. Ovaling is thought to create dispersion. I have seen various materials use in this area to stabilize driver shafts. I have never seen as dramatic an effect on hoop deformation as I see in the Tensei Pros. Take note, the OEM shafts have only 4″ of this material which is little more than cosmetics. The Tensei Pro models have 11+” and the hoop deformation profiles are dramatically lower in this area.

Aldila XTorsion Golf Shaft Review

Aldila XTorsion Copper & XTorsion Green  Shaft Review

The Aldila Xtorsion driver shaft have a clearly visible woven material in the lower half of the shafts. Aldila calls the material, MAMBA, Multi-Axial Material Bias Angle technology. It is woven at a 45 degree angle which provides torsional stability to the lower half of the shaft where it is most important. This can be seen in the GJ or torsional profile of the shafts. The GJ profile tips downward from the mid section to the tip. I also see high and stable hoop strength resulting from the woven material. This is similar to the woven section of the Mitsubishi Tensei Pro shafts that is located just below the grip. When I look at the Xtorsion Copper EI profile I am reminded of the very popular EI profile of the Nippon Modus 120’s.

KBS $-Taper Lite Golf Shaft Review

KBS $-Taper Lite Iron Shaft Review

Following the success of the KBS C-Taper Lite, KBS now offers a Lite version of the $-Taper. It comes in three weights, 95, 100 and 105. The profiles are nearly identical to the $-Taper. The three weights offered are less than the $-Taper 110 gram R. The $-Taper Lite weights, in my experience, are a perfect fit for the recreational golfer.

If you do not follow my YouTube Channel, Devoted Golfer, you may have missed this video. We shot the 2019 KBS presentation to golf club fitters at the PGA Merchandise show. It covers the entire product line. After the slide show, Kim Braly comes to the podium and talks about tour acceptance of 2018 KBS shafts and the new 2019 shafts.

As you can see in this table, the weighs of the $-Taper Lite extend the weight range of the $-Taper.   This is different than the C-Taper Lite and the C-Taper where there is an overlap with the C-Taper R and R+.

True Temper Elevate Pro Golf Shaft Review

True Temper Elevate Pro Golf Shaft Review

The True Temper Elevate was designed to launch the ball higher than it counterpart, the Dynamic Gold 120. Bill Lange explains the Elevate in this video shot at the PGA Merchandise show the year the Elevate was launched.

The Elevate is a traditional “Dynamic” design. The length from the shaft tip to the first step changes with flex. R Flex has a long tip section, S shorter and X shortest. There is also small increase in weight as stiffness increases. This image illustrates how that tip length changes the EI bend profile of the shafts. Lets take a close look at how this dual change in profile and weight influence stiffness and set makup.
