I'm for 5-setters. Love to play them. Some of my most memorable moments on a tennis court are 5-setters going the distance with me winning most of them. Some people say that people want best of 5 sets because they can't win in 2 or 3, maybe,.....but I just like playing best of 5 when I get a chance. Definintely a different game, and it just has a special kind of atmosphere that I seem to pick up on during the match that makes playing tennis so much more rewarding and enjoyable.
