ABSTRACT:
A construction of a string of the type used with a plurality of other such strings, in connected fashion across the head of a sports racket, such as a tennis racket or the like, wherein the string construction is defined to include various structural components to enable an interaction between the strings and a ball being struck thereby so as to make it easier to control the flight of the ball, after it is struck and also to overcome any natural derogatory tendency of a person's swing that would tend to derogatorily affect the flight of the ball.
