Argument based criticism is valuable, no worry...
Last year, when I changed the bounce for TE2006 I expected many reactions, but I got none, and this time, I already have a few, so I guess last year changes were better...
Actually, you're going to have trouble to restore the bounce of previous version only by changing back the court properties, coz actually, it seems the change that annoys you the most is the one about the top spin effect that occurs on the ball rebound (I guess no other game handles that, and it was just introduced in TE2006).
I'm going to set it back to something closer of previous version, while still staying close of the new court properties.
One of my motivation to change the rebounds was that the top spin effect (b1 + down) doesn't produce a high enough rebound compared to what I can do on a real court, I think in the new version is more realistic about that point...
