This is the current model shaft used by Hideki Matsuyama! It's a high-performance club with a GD-6 driver using a carbon head, flex S. The head alone is worth tens of thousands of yen! Negotiations are welcome, so please feel free to inquire. - Model: GD-6 - Flex: S - Type: Driver - Head Material: Carbon Used only about twice in practice. I'm selling it at a low price because I don't use it! No claims and no returns, please.
