Only +am3 sets stochastic rendering. I like it but it is much slower imo 
when set to high quality like +ac99. However, I may be wrong as I have 
not compared renders seriously. Clipka would know ;-) I little bit of 
grainy image is not a problem to me although it is difficult to balance 
quality versus (acceptable) render time. I am not always that patient.

With Dhalgren, I used +am2, so no stochastic rendering there.

Hum... I am a bit reluctant to have a bite :-)
