Results Stringing makes a significant difference in how a frame plays. Gut is best for playability and synthetics are best for players seeking durability. With the improvements in synthetic fibers, however, many synthetic strings offer a superb balance of durability and playability. Stay within the manufacturer's recommended string tensions that are determined to maximize frame performance. For more power, string the racket at the low-end of the range.
Lower tension equals more power.
Higher string tensions give less power but more depth control. Restring your racket each year as many times as you play each week. Always restring at least once a year.
