i think you are talking about the indoor tournaments,Peter M said:Hingis attributed her poor fall season last year partly on the faster European hardcourt. She said her reduced speed (due to her injury) was not exploited as much during Canada/New Haven/NY as it was in Filderstadt/Swisscom since the hardcourt was slower in the States.
Har-Tru is American "green" clay. Supreme is certainly "carpet." But, I was always under the impression that "greenset" was a type of hardcourt. Could be wrong about that, though.
so most of the stuff is fast except Indian WellsTheBoiledEgg said:Indian Wells is played on PlexiPave Hard Courts
most use Decoturf though
not much difference, just location, altitude
AUS has Rebound Ace, but Gold Coast event uses Synpave (similar but not so sticky in heat)
