We all know that pros (especially top ones) restring their racquets after every practice, or at least that what I read in tennis magazines. However, at recreational level, I have heard my friends telling me how frequently they restring their racquets (every two weeks/six hours of play), regardless if the string popped or not. I personally use multi string (NXT Tour 17) and use it even when it start to rout. I use multi because of its feel and the fact that with my game I won't get a surprise string pop as I will only expect a pop as it deteriorate. Yes, of course I can feel the freshly restrung racquet's pop but as the string deriorated I only notice the falling tension, not necessarily the "deadness" of the string. Comment coming from a friend who doesn't necessarily have a touch game, what do you guys think he means when he says he feels the string is dead? Is it just mental?
