Brand: PING #7 to #Pw G400. Tour AD 65 II Flex S (Genuine custom shaft installed by the manufacturer) #6 G410 Tour AD 55 Flex R The AD65 Type II shaft is currently being used by Shin Ji-e. #6 was specially made to be slightly lighter in balance to make it easier to get the ball up in the air and easier to swing. I believe it has been finished into a club that is not just light, but also has a solid feel when swung.
