I like having a variety of hard court speeds, it adds to the excitment and gives us a look at different players and different styles, also its only fair to have varying speeds because if the speed was fast on all then certain players would have a constant and extreme advantage over other players and vis-versa, this way all players have to play on surfaces they are both comfortable and uncomfortable with and the playing field is level over the course of a year, maybe what they should do is actually play less on hardcourts because they make up 60% of ATP tournys and the players better on hard courts are at an advantage rankings and earning potential wise, maybe they should have a few more clay, another week of grass, and perhaps a few more indoor carpet, thats a huge change though and would never happen even if it would be the most fair
