Over the weekend I got to hit with the Pro Staff Original 6.0 St. Vincent version that I recieved last week and WOW. I now realize why people love this racquet. I served better, volleyed better, and yes, I even hit groundstrokes better with a racquet that many feel cannot be competed with in today's game. I'm 19 and though I've tried all the popular player's racquets, the Pro Staff is the only one that I feel combines the great features of all of them. You do have to up your level of concentration to play with this racquet and you cannot be lazy in any respect, but I may very well make the switch.
