Excuse my ignorance: I have a few of the same Head Prestige Classic 600's with the Star Trek font and made in Austria on them. I've had them since I played juniors back in 93-96. I had the grips beefed up a few years ago so I could keep playing them. I keep seeing all of the actual stock names that everyone refers to each model with and I was wondering how I can tell exactly what model I have? All it reads is the suggested string tension and the pattern. There is a sticker still there but it has obviously faded away. Any help is appreciated. It's been my racquet of choice throughout the years of playing on an off.
