Tensei Hybrid 80s shaft with Callaway's old sleeve, compatible with Ai Smoke, Paradym, Rogue ST, etc. This shaft is in excellent condition, having only been swung once at the driving range after I ordered it, as I decided to use a different utility shaft. It offers a smooth flex and is suitable for a wide range of players, so if you're not satisfied with the stock shaft, please consider this one. I'm open to questions and price negotiations, so feel free to ask if you're interested.
