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.

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 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. This is the first of many reviews of the 100+ shafts that arrived. They have created heavier, stiffer shafts for the US market. And, in many models they offer matched driver, fairway and hybrid shafts.
