When I entered the golf club fitting business about 15 years ago, there wasn’t any way to compare golf shafts. There was no standard rating system for golf shaft stiffness. That was and still is a problem for understanding what shaft is best for your game. Describing golf shaft properties is not a simple task. So as the saying goes, necessity is the mother of invention. Shaft company marketing staff developed terms, “kick point”, “stiffness”, “launch” and “spin” to describe shaft properties. These terms developed into a mythological language for describing golf shafts.

However, shaft engineers and designers define golf shaft stiffness as a profile, the shape of stiffness down the length of the shaft. I learned the terms EI and GJ in discussions with shaft engineers. I was fortunate to have the opportunity to tour a shaft company R&D lab and my understanding of golf shaft technology was shaken to the core.

I designed and manufactured a simple but very accurate EI measuring instrument. It is now owned and used by several shaft companies. I have been writing about EI profiles on this journal for 7+ years. At last, the term EI profile, is part of the discussion shaft companies are having with golfers.

Golf Shaft Reviews is my freelance journal about golf shafts. If you want to understand golf shafts you have come to the right place. Here you can learn why some shafts work for you and others do not. I encourage you share your comments about what you experience with the shafts reviewed. Learn which profiles work for you and which do not. There is a great deal to understand beyond the marketing mythology used to sell golf shafts.

Creating a uniform system to define the distribution of flex down a golf shaft was possible, in fact most shaft companies have such systems. But the information, for fear of giving that information to their competitors, is not shared with golfers or golf professionals. It took a few years to refine my EI Instrument and many, many years to acquire and measure the popular golf shafts. This journal provides you with uniform measurements of thousands of golf shafts.

If you are new to my journal, the technology menu is a collection of articles that will help you understanding golf shaft design and the attributes of the golf shaft that can be independently measured. My objective in creating this journal is to balance the marketing messages of the golf business with some science. And ultimately, help you make better decisions about your golf clubs.

This journal is entirely supported by reader subscriptions. If you believe as I do, that your golf shafts are essential to good golf, please subscribe. Testing shafts and writing articles takes a great amount of time. Your subscription underwrites the time and resources needed to keep my journal going and growing. You will notice, this site is does not run ads, that allows me to remain unbiased in the articles.

This video is a detailed discussion about golf shafts stiffness and the history of how they were measured and marketed. It is one of many videos about golf equipment technology and golf club building on my youtube channel.

It took years to understand shaft measurement and many more years to accumulate a meaningful database of shaft measurements. The magnitude of that accomplishment did not occur to me until a golf shaft company owner said it to me. Several golf shaft companies now use the EI measuring instrument I designed and manufactured. If you are a golf professional and would like access to more data there are two choices. Golf Professional subscribers get access to a larger set of data and individual profiles of all the shaft model weights and stiffness variations that were made available. Fit2Score Affiliates have access to the entire database through Excel. To hear a recent podcast interview I did about golf shafts with Tony Wright, a Fit2Score Software Affiliate, Click Here.

The Mitsubishi Tensei pro 1K Orange is the second shaft model using the thinner Carbon Kevlar woven material just below he grip. The tip is Mitsubishi Chemical’s MR70 that is claimed to be stronger and more elastic than typical carbon fiber materials.

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

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.

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.

Dynamic Gold 95 Iron Shaft Review

Dynamic Gold 95 Iron Golf Shaft Review

By Russ Ryden, Fit2Score, A Dallas Fort Worth Club Fitter & Builder

I have just learned to say True Sports instead of True Temper. Then the name changed again to TrueTemper Sports. That makes more sense, but all those words are much to long for the fields in my database. Hence, TrueTemper Sports is abbreviated to TTS.

Another name change I embrace is the expansion of the Dynamic Gold brand name applied to weight variations of the design. No longer, at least for the moment, will the Dynamic Archetype in different weights bear a different model name. More on this later in the review. For now, lets just say the 95 gram version of the Dynamic Gold fills out the line which now includes 105, 115, 120 and the original 130 gram models.
