This is a shaft compatible with Tensei Hybrid 90s Callaway old sleeves, Ai Smoke, Paradym, Rogue ST, etc. I ordered it and it arrived, but I decided to use another utility shaft, so it's in excellent condition, only swung once on the driving range. It has a straightforward flex feel that is universally appealing, so please consider it if you find the stock shaft lacking. I am open to questions and price negotiations, so please feel free to contact me if you are interested.
