Iso TI SP (SX, SS, SA, etc..)
To those who played with the Iso TI SP racquets on the two ends of the stiffness scale; What are the differences between the racquets (benefits/drawbacks). What does the stiffness of the racquet affect? When they rate stiffness, they are referring to the strength of the shaft of the racquet?
