Of particular interest is the frame composition of 80% graphite and 20% kevlar. The high percentage of graphite allows for a 'softer' feel, while the kevlar provides more strength in the frame. Also unique is that the graphite in the Pro Staff Original is braided. While more modern racquets consist of many pieces of graphite spliced to the framework of the racquet, the braided graphite construction of the Pro Staff Original was such that only a single, long piece of graphite is used, which is then 'braided' around the frame. This created more strength and stability in the racquet, while increasing the weight of the frame.
