Graphite Design TOUR AD DI-7 TOUR AD DI-7 Black Flex: S Length: 1061mm Used in a Titleist 3-wood. I used it in imitation of Hideki Matsuyama, who also used the black color in his 3-wood. Can be installed on Titleist fairway woods. There is a slight gap in the socket and scratches on the sleeve. I used it in this condition for a while, so there is no problem with use, but please use it at your own risk. Series: Tour AD Series Tour AD Series / Model Name: Tour AD DI-7
