My old club pro told me once, "Grim, it's the newest thing. It's called the Wilson Profile. Pretty soon, every pro on the tour will be using one. It's got so much power, it's going to revolutionize the game! Just you watch! 200 mph serves!"
My old club pro was a horse's ***, and Siegfried Kuebler owes me an apology and a Guinness for what he did to the elbow of a starry-eyed kid dreaming of a 200 mph serve.
