I have been fitting with Mitsubishi Diamana Golf Shafts since I started my fitting business. The Blue Board Archetype is the most copied shaft profile in the business. The soft mid profile delivers forgiveness to the often erratic tempo of many recreational golfers. the last three generations of the Diamana have changed very little. The Diamana BB is a significant change.
This chart compares the torque of the last four generations of the Diamana Blue golf shafts. Mitsubishi tells us high modulus 46 ton fiber was used in the bias plies and 80 ton fiber is used in the butt section of the Diamana BB. It is evident that torque, as claimed, has been reduced. The torque of the BB is 0.4 degrees lower than earlier models.

The LA Golf G series is now available in limited quantities.It is made on a 16 sided mandrel unlike the typical smooth mandrel. As you will hear in the video, Jeff Meyer blind tested the same materials in a smooth mandrel and the 12 sided mandrel with some of the top tour players. The feel of the 16 sided mandrel was universally prefered. He talks about some of the other technology in the shaft in this interview. Just recently, the 60-6 model arrived. Those that have tested the shaft have asked for a stiffer model.
If you want to see if a $1000 shaft works for you, schedule a fitting at the Highlands Performance Golf Center or with Fit2Score where we have the full line of LA Golf shafts in our fitting system.

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 850 GHneo Iron Shaft Review
Nippon 850 GHneo Iron Shaft Review

A companion to the Nippon 950 GHneo has just been released, the 850GHneo. New graphics on what is essentially the N.S Pro 850. When the 950GHneo was released I mentioned that almost every fitting cart still included the N.S.Pro 950 despite its long outdated graphics. That was not the case with the N.S Pro 850. It had never been been widely present in the club equipment fitting carts. I have been fitting Nippon steel for a long time. In fact I wrote an overview of the entire N.S Pro product line 9 years ago in the second year of this journal.

Nippon Regio Formula Plus Driver Shafts Review

It has been 9 years since I looked at the first generation Nippon Regio Driver shafts. That review included only one of the three models. In this review, all three models were measured and compared. While Nippon is well know for their iron shafts, the driver shafts in the US are not popular. That is an understatement, they are virtually unknown. Over the last several years a few of my long term affiliated trainers and players have raved about their experience with the Regio Formula Plus driver shafts.
If you do not follow my YouTube Channel, Devoted Golfer, this is Mark Pekarek discussing the N.S. Pro Regio Formula + driver shaft designs:
As with all Nippon golf shafts, the quality and consistency of the Regio Formula Plus Shafts are second to none. They are all made in Japan, expensive, and reflect the attention to quality that we expect from Japanese made products.

UST LIN-Q Driver Shaft Review
UST LIN-Q Blue & Red Driver Shaft Review

I have limited access to UST shafts as they do not provide review samples. In looking at the UST website they have provided accurate EI profiles of the LIN-Q product line. I would expect as much as they own one of my EI instruments. Carbon fiber materials are constantly being improved. UST tells us that they used the latest generation TORAY prepreg in the LIN-Q.
