Firstly, the surface should have stayed Rebound Ace. If there was an important reason to abandon Rebound Ace then fine, but I don't see it, and it makes AO appear to be a lesser version of the US Open. It should have avoided all comparisons by sticking to that higher bouncing slightly slower Rebound Ace.
I personally much prefer the green courts. Blue is kind of dull to me. Green for some reason makes more of an impression and just overall its better on my eyes
