Roger Federer may be around for two or three years but the issue is beyond that.
No one is asking to make all the courts faster. But how could youaccept slowing down of almost all surfaces? Except for Cincinnati all the surfaces are slow.
Let it be this way
Australian Open - medium slow hard court, Rebound ace
RG - the 90s slow clay
Wimbledon - the 90s ultra fast grass, come on it's such an insult to see baseline Tennis on the hallowed surface of Wimbledon. Even if it's Karlovic v/s Isner final, I don't care but bring back old green grass.
US Open - fast hard courts like 90s
That way we have variety
