I am seriously beginning to lose interest in tennis as a professional sport. The ATP tour are destroying the sport by slowing down every court worldwide. Isn't it time they sped some of the courts up?
There are a few that have been sped up, it's not all one-way. Indoors Rotterdam was quicker this year, and Paris has been sped up a ton (a few said it was the fastest court they'd ever seen). Quite a few of the European indoor events have got a bit quicker in 08/09 too, as they went from Greenset to Gerflor. Moscow moved to a quicker version of Rukort.
Outdoors Tokyo has got faster this past year, Nadal said it was the fastest court he'd played on. Montreal this year was also quicker than in 09 (which may have been a mistake, as it was pretty quick in 05/07). Delray is using a quicker plexipave, and Winston-Salem is a lot quicker than the event it replaced (New Haven). Cincy is as quick as ever.
Having said all that, at the big events: Miami and IW are as slow as ever (they're rated medium/slow on the ITF scale). Shanghai replaced an indoors event in Madrid, but it's much slower (also I suspect a medium/slow).
At the majors they've explained what happened with the US this year, I'm sure they'll fix it for next. It is supposed to be identical to Cincy, after all.
