I have predominantly used Head and Wilson racquets most of my tennis life. I am curious if anyone knows what the approximate percentage of market share each of the major racquet brands has in the US or World market. I remember many years ago one of the largest dealers in Michigan, USA told me that the Babolat Pure Drive racquet outsells all of the other racquets COMBINED! I'm contemplating trying the Babolat for the first time, just wondering what people know and if there is anything special about the woofer technology that makes it a better racquet, or better racquet for serving. Thanks.
