Polyester tennis strings are used prolifically on the ATP World Tour, but are they the right strings for you?
Professional players love the spin and control they get from polyester-based tennis strings. Stiff in nature, the polyester strings allow pros to control all the power they generate on big strokes by deadening the response of the racquet. With professional players flocking to polyester strings over the past decade, their popularity at the amateur levels also soared. But what is best for the world's elite might not bring the best performance to those of us playing at clubs, parks and public courts. Amateurs rarely hit with the same amount of power as professional players. Even on the occasions we generate big power, we don't do it with the consistency of the pros.
“PU multifilament string, first and foremost, provides a higher degree of shock absorption at ball impact,” Dorsey said. “When you combine less-than-stellar mechanics with a lighter-weight, larger head size racquet, vibration and shock become a real problem. Polyester monofilament string only compounds the problem of shock. Over a one-and-a-half hour match, a PU multifilament string will absorb more shock and generate 22 percent less fatigue than a polyester string.” A softer string is more comfortable because it uses less force over a longer dwell time to rebound the ball. However, since a stiffer string has less power, a player may be able to swing harder, hitting the ball faster. But there's a big price to pay for that extra speed – more energy input and even larger impact shock.”
Multifilament strings also tend to be much better at holding tension. You should find a more consistent response over the course of the string's life with it in your racquet compared to polyester strings. With polyester strings we recommend restringing your racquet with a fresh set of string every three to four weeks to get the best playability. More frequent restringing is even better with polyester monofilaments due to their increased tension loss. On the tour players are using fresh strings for every match with some players switching to fresh strings at every ball change. Obviously this is not cost effective for amateur players, but if you are using polyester strings restringing once a month will get you the best performance from the string bed.
With a multifilament, players can generally restring in a year as many times as they play in a week. For instance, if you play four times a week, plan on restringing four times a year for the best performance.
