Tensei Hybrid 90s shaft with Callaway's old sleeve, compatible with AI Smoke, Paradym, Rogue ST, etc. This shaft arrived after I ordered it, but I've decided to use a different utility shaft. It's been swung only once at the driving range, so it's in excellent condition. It has a smooth flex, making it a shaft that suits everyone. If you're not satisfied with the stock shaft, please consider this one.
