There's always been speculation about the racquets the pros use, and whether the racquets they use are actually as advertised. Roddick has been quoted as saying something to the effect that (I know it's not an exact quote) the racquet he uses is basically the same thing you can buy from a tennis shop. Fine, let's take Roddick's racquet after a match and compare it to the retail. Ask other pros to provide their match racquets for comparison. Why be so secretive about it? If you were an elite tennis pro, wouldn't you want your talent to be attributed to your innate and developed skills, and not modifications to a racquet or a paintjobbed racquet? It's the same thing with performance-enhancing drugs: if I were a clean athlete, I'd gladly provide a blood/urine test to show that I don't need no stinkin' steroids to enhance my performance.
