Becker was more vocal than most about his undying love for his old Puma/Estusa frame, and he even went so far as to purchase the mold after Estusa stopped making it. In recent years, however, there has been a racquet designated as "Becker's personal frame" in the Becker/Volkl line. Is there a story to the change? Did he sell the mold before getting involved with Volkl? Did he really change such a strongly held preference, perhaps needing a bigger head? Was it purely a business decision (i.e., Volkl having no use for the old Puma mold and Becker playing so little tennis that a current Volkl frame was adequate while being far more profitable to endorse)?
