My club now has three indoor surfaces.
The oldest is green carpet, which is the original surface. This bounces lowest and is fastest.
The second is orange carpet, with a navy run-off area. These were installed this year. The carpet is thicker, the ball bounces higher and slower than the green. Curiously, slices sit up. The orange and blue kinda hurt my eyes.
The last is acrylic, which were completed a couple of months ago. They are two shades of blue, and look lovely. The ball bounces higher again, though slice shoot through low. Initially they felt faster, but once I'd had a couple of goes on them I realised they were actually slower than the green carpet. They absolutely eat balls, and are probably going to kill my shoes much quicker too.
Outdoors we have astroturf, though I have suspicions that it's actually the same carpet they used inside with a load of sand dumped on it. They are built on a landfill, uneven, and are possibly the worst courts I've ever played on.
