Okay everyone, here's my dilemma: I purchased a Wilson Sting a few days ago (midsize) and I have been hitting with it against the wall and with assorted hitting partners. To sum it all up, it's a beast.:twisted: I feel like I'm hitting better, manipulating the ball in a way I wasn't able to do before with my PK 5g. I'm not spraying the ball, not hitting outside the baseline as often, the 1hbh is effortless and concise, and my concentration has never been better (probably due to the 85sq. in. head.) My strokes have pop and placement but I have not played a match with it yet. Also, I might want to string it up with some gut. This racquet has exposed any irregularities in my technique, thus I'm able to concentrate more on playing rather than just trying not to screw up. However, I'm a little bit frightened to be matching power with players with the newest frames. Will the Sting break down? Will it inevitably let me down in crucial moments? Will there be immeasurable frustration, "Man, if I had my PK 5g that wouldn't have happened!" What does science say about the classics butting heads with the newest sticks? It seems to me that the Sting could hold it's own, but I might be wrong about this. I am a topspin player, SW grip, all courter. I know there are a bunch of you who are tried and true vintage racquet players, I'm just looking for some feedback. The Sting is a very special racquet and I know there are going to be some "growing pains" with it, but in the long run is it practical to make the switch to this legendary stick?
