That should give prety smooth results in most cases. Using 
Antialias_Depth=9 is very probably overkill, a value of 3 or 4 is usualy 
enough. There is a default value that will be used if you don't set 
Antialias_Depth.

To get smoother results, reducing Antialias_Threshold is normaly all 
that you need. Keep it larger than 0.0 or your render time will 
skyrocket as each pixel will get uselessly antialiased...
