There are many posts here about the St. Vincent Pro Staff 85 used by Pete Sampras. Did Edberg and Courier also insist on a St. Vincent? Late in their careers, Edberg had a pj and Courier had an all-black racquet that looked like their old Pro Staff racquets. Were these any different from the racquets they used at the start of their careers? In the early nineties, I played with Wilson Pro Staff 85's made in Taiwan with braided graphite. I took time off from tennis and then shelved the frames because I found it hard to generate topspin and got frustrated with how rapidly they broke strings. I recently took them out of storage and love the feel and the way they can hit a ball on the dime, but heavy topsin is still a problem. Anyone know how these Taiwan frames differ from the St. Vincents?
