I am now experimenting with a Wilson Pro Staff X v 14.0. I hit with a demo from Tennis Express for a few days and now am moving along to Phase II of buying and playing consistenly with this racket. So far, I am impressed. As a tennis court rat since 1972, I have used and seen a lot of rackets come and go. I am a mostly life-long user of the Wilson Pro Staff line. Soon I will post my feedback on the latest of the Wilson Pro Staff line.
