Using my Yonex from the 70's, an awesome tennis racquet. Don't let them (racquet makers) tell you lies. Today's racquets aren't any better than racquets such as this one and the Wilson T-2000. They had to stop making the T-2000 because it lasts forever. They want to make racquets that don't last so you have to go buy a new one every year. And they want to fool you into thinking that they are coming up with new technologies that will improve your game. Wake up tennis players! If you want to improve your game, concentrate on your fitness and skill and compete. The better players always preferred heavier racquets and smaller heads. Take a look at Sampras with his 85 sq inch Pro Staff. They don't make that size anymore. Not because it is not bad but because of demand from consumers who think bigger is better. Smaller head means more maneuverability. It can be proven scientifically. The formula P= mv means momentum equals mass times velosity. Smaller head means greater velocity. Heavier head means greater mass. So you get more momentum with smaller heavier head and that translates to more power, does it not?
