DGA developed this disc to help sink your putts! The D Line Titanic is a slightly over stable putt and approach disc that was designed to sail straight and nail your shots. More stable than the Reef, this disc will hold a long hyzer putt line. The D Line Titanic can be used for flex shots when approaching and can hold a steady line. The Titanic in D Line plastic has enhanced grip and durability that sets this putter apart from any competition.
