Korean Hidden Technology AutoPower Flex 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 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.

There have been a lot of ultra light golf shafts released in 2024 and 2025. The Mitsubishi Vanquish is the recent release aimed at this market segment. I remember the Bassara UltraLight Mitsubishi models from 2014 – 2016. This series was discontinued and Diamana models became available in lighter weights. Currently the Diamana models are offered in 40 gram versions. The remaining ultra light is the Grand Bassara which gets down to 29 and 39 grams. While I typically avoid working with shaft ultra light shafts because of their high torque. I did have a customer that developed his swing around a Grand Bassara and hit it further than anything else I tested. The current batch of Vanquish review shafts is available from TaylorMade in 2025 at no upcharge.

The Kai’li Dark Waves series of shafts is included in the 2025 TaylorMade Custom Shaft Options catalog as a no upcharge shaft. The Kai’li name goes back to to my early days of shaft profiling. When it was used as part of the Diamana model family I recognized as a Blue Archetype. Over the years the name was reused in 2023 with White, Blue and Red models. I have limit access to the new Dark Wave Kai’li models from the TaylorMade shaft options catalog which will be expanded as missing models arrive. Rather than posting separate reviews for each model I will cover the White, CB, Fairway and Hybrid models is this overview.

Graphite Designs Tour AD VF Hybrid Review

Graphite Designs introduced the Tour AD VF, Victories requires Force, driver shaft in late 2023. The Tour AD VF Hybrid Shaft released in 2024. The profile is a close match to the VF driver profile. . Stiffness is generally a function of weigh as you can see in the chart below. The uncut weights range from 77 to 107 grams. This wide range is similar to the wide weight range available on the VF driver. The torque numbers illustrate the low tip torque achieved by using Torayca T1100G woven fiber in the tip of the VF Hybrid shaft.

As you can see in the EI profile, the shaft profile is indeed as claimed. the tip section is firmer than all other Graphite Design Tour AD Hybrid models.
