[I've used both the Symphony and the PIS extensively, though not the  
PISA. No commercial relationship.]
My primary problem with the PIS, as well as it being a little less  
effective and not as good at maintaining supply for me, was it being  
uncomfortable compared to a Symphony, regardless of settings. The  
vacuum profile felt like a nagging sudden tug-tug-tugging instead of  
a smooth rhythmic expression. I also found the noise of the PIS to be  
much more irritating. Both of these factors added up to shorter, less  
relaxed pump sessions.

If these factors play in, I don't know whether simultaneous use on  
each breast will give you all of the answers you're looking for.  
Perhaps alternating pump sessions with one double pump, then the  
other (keeping a close record of timing) may be a useful experiment  
also?
