HSV Stringing's best-selling string. The Ytex Quadro Twist is a four-sided poly that generates serious spin without punishing your arm — a rare combination in a co-poly string.
The twisted, square-edged design bites the ball and snaps back quickly, giving you extra topspin on serves and groundstrokes. At $15.75 per set, it's one of the best-value spin strings in the shop.
