a little side comment away from the players - i went and try out the new court surfaces at olympic park yesterday, what they called the plexicushion. it does fluff up the ball a lot more than rebound ace, and it is a tad slower (which i enjoyed), but the bounce is still there. i like to dice up the ball a bit during points, and it really bites and turns for you, more than clay i'd say. overall i am one of the few who are actually happier with the new surface, it's gold.
any tennis enthusiasts should try it out.
