I do not think so. Pro's use HEAD'S PT or TGK models, made in a special part of HEAD HQ in Austria. They change the paintjob every 2 or 3 years, to increase sales. Technology is 90% marketing, but are exceptions, and O3 ports of Prince are one. The frame's molds rarely changes. You see a Pro Staff mold (Federer) and know that has more than 20 years. The PT 57 mold has more than 15 years and still used by Murray and many others.
Pro's do not change their equipment so easily. Think Sampras, Federer, Roddick, Nadal, Murray. They have the same racquets for years..........
