The CL 633 is a professional racket with absolute ball control. 18 main strings and a continuous box profile provide perfect feedback for players. Strokes without loss of feeling and a long grip for two-handed playing merge this sport equipment together with the player so that they form a single entity. Thsi racquet is the most control oriented racquet from the Topspin line. This is a similar racquet to the Head Prestige series, and the Wilson n-code six-one series.
