The Mitsubishi Kaili Blue CB is another no upcharge option in the 2026 Taylormade Custom Driver / Fwy shaft options. The 2026 TaylorMade fitting system designates shafts to match a player’s rotation profile as follows:
HR – High Rotation Designed for players who release the club early, with the shaft lining up with the lead arm before or at impact. The shaft is a soft-tip profile to aid in closing the face.
MR – Mid Rotation Designed for players with a neutral release, with the shaft lining up with the lead arm just after impact. The shaft is a middle-of-the-road tip stiffness.
LR – Low Rotation Designed for player who hold the release, with the shaft lining up well after impact. The shaft tip is stiff to prevent the face from closing too quickly.

While other shafts with the rotation designation reference tip stiffness, the Kai’li CB ratings appear to be entirely stiffness related. that is not an issue from my perspective.

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.

Korean Hidden Technology AutoFlex Driver shafts came to the US market several years ago. I saw one in 2021. They caused a sensation with a $790 price point. 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.

I met with Korean Hidden Technology at the PGA 2025 merchandise show and shot an interview in their booth. They followed up with a shipment of review samples of every SKU they make. This is the first Korean Hidden Technology shaft that was available in the US in 2021. I had access to a single shaft then unlike now that I have measured all the shafts available at https://autoflex.us/. It was no small task measuring the 100+ shafts they supplied. KHT makes driver, fairway and hybrid shafts in each model family. Some models also have matched iron shafts. This is unique. The autoFlex is available in 4 color choices. That added some confusion to sorting the review samples. You must ignore colors and focus on the model designation printed on the shafts.
