I purchased a new G425 MAX driver at Tsuruya Golf and have been using it for about a year and a half. Both the sleeve and grip are the same as when I bought it new and haven't been changed. I play about once every three months (practice the same amount), so I don't think the grip is very worn. The shaft is X flex, and when I had the frequency measured during fitting, it was 272, so it's for hard hitters. #ping #shaft
