i wouldn't call them different surfaces like clay and grass........they are still hardcourts retain all the basic characteristics of a hardcourt at the end of the day........just different mixture of materials used........to me historically decoturf-2 seemed faster except for 2011 edition when their paint job went horribly wrong impacting the surface speed........
plexicushion looked medium fast when it was first introduced in 2008 but in 2012 wonder what they did it played slow as hell, rafa would have won that title had it played a bit faster than that or at least it was a day match........people don't understand rafa's game, he likes fast playing hardcourts, not the slow types........
