7 different weight/balance options for the person who likes to customize their own feel. 3 x ½ oz weights that let you decide the feel you want before you permanently mount them. This allows you to adjust both how much you add, as well as where. This system allows you to mount the weights further away from the center point to allow more affect on the balance of the club. Just like a real club, we want you to get the feel you like because in the game, that helps give you that feeling of immersion.
