Why do you want the courts faster? Do you want guys like Raonic and Karlovic winning slams? Because if you make the courts fast enough, they would. They have some of the best serve numbers in the game. Both guys have sub 20% return numbers though (Karlovic is 6% on hard courts, which is so bad I don't have an appropriate adjective).
These guys would win big tournaments on lightning fast courts.
This argument is so shit. Raonic and Karlovic wouldn't even win slams on early '90s grass. Even the biggest servebots of the '90s (Stich, Ivanisevic) were far more complete players than either of those guys.
Nobody is arguing for those sorts of courtspeeds anyway. People just want a return to the surfaces of 9-10 years ago, where you actually had variety. Servebots didn't dominate the USO and Wimbledon in the early '00s.
I have no idea why people think that wanting the courts quicker than their current molasses speed means you want ice rinks that people serve their way to victory on.
