it hax been years since I measured a SteelFiber Shaft. True Temper acquiered Aerotech Golf in Demember 2019. I knew Chris Hilleary who launched Aerotech Golf in 2001 and passed away unexpectly in 2021. Its best to have Chris explain Steelfiber shafts:

Chris taught me how to measure hoop strength. I added hoop deformation into my software system. It later became essential for removing the distortion of EI measurements inherent in the 3-point process of measuring golf shafts. Textbook EI measurement is built around measuring solids. Golf shafts are tubes which deform during play as well as during measuring. After measuring distortion of a great number of shafts as each of the strain points, we learned we could forecast those distortions by applying known hoop deformationof the golf shaft tube.

KBS Players Graphite Wood Shaft

The Players Graphite Wood is a 2025 model released in late 2024. This review is late due. I did an interview with Kim in early 2025 where he described the shaft and designed for the recreational golfer. Certainly its $175 will be appealing to the recreational golfer not comfortable with the $300+ prices of high end graphite shafts.

And yet, at that price, the profile in not to far off from some of the Graphite Design Tour AD’s and Fuji Ventus models.

Graphite Designs Tour AD FI Driver Shaft

The Graphite Design Tour AD FI (Flight Intelligence) Driver Shaft released in September 2025. It incorporates some new technologies as well and the latest Torayca fabrics. As my understanding of these fabrics grows, I can see how they influence the properties. Looking at Graphite Design’s Bend Profile ratings, the FI is one of the higher rated shafts in the Mid section with a 3+. The GC is rated 3 and the VF is rated 4. A see high mid stiffness as an Archetype design. The FI is firmly a member of the midfirm archetype. The GC and VF less so. Over the last two years, when I recognized the midfirm archetype, I have fit numerous great ball strikers into the design. While I have come to recognize midsoft as forgiving, a midfirm shaft is unforgiving. Like an iron blade, it is workable for those that can shape shots at will.

The Graphite Design Tour AD FI is without a doubt a member of the midfirm archetype that is my go to design for low single digit and plus handicap players.

The Nippon Modus3 110 is the third Modus3 shaft from Nippon ending with a 0. First was the 120, then the 130, now the 110. The moniker is a rough approximation of the weight, but also an reference to a unique bend profile from Nippon. Those shafts ending with a 5 are the same profiles with the numbers, 105, 115 and 125 indicating weight. In the Modus3 110 family, the weights range from R at 103g, S at 109g and X at 114 grams. Weight directly correlates to stiffness as it does in all steel shaft

Korean Hidden Technology autoFlex Dream7 Driver, Fairway and Hybrid Shafts

Korean Hidden Technology autoFlex Driver shafts came to the US market several years ago. I saw one in 2021. They cause a sensation with a $790 price point. They were very light weight and started a trend for light weight driver shafts. Ultimately most US golfers were not ready for light weight shafts at that price point.
The autoFlex Dream7 is a second generation autoFlex. It is lighter than the original model made with updated Japanese prepreg and 2nd generation Korean Hidden Technology. According to KHT the Dream7 has a new tip section to enhance impact performance.

They were very light weight and started a trend for light weight driver shafts. Ultimately the recreational US golfer was not ready for light weight shafts at that price point.
I met with Korean Hidden Technology at the PGA 2025 merchandise show and shot an interview in their booth. It is on the list of videos that need to be published. They followed up with a shipment of review samples of every SKU they make. I don’t see much difference between the Joy365 and the original autoFlex shafts. The autoFlex website tells us the Joy is made with updated prepreg. the measured differences are subtle. Without hitting them I cannot comment on feel.
