pretty straight forward??  It does makes for better harmonic 
suppression without a doubt. >>

That statement is so all-encompassing it is wrong.

There isn't any rule carved in stone that says just changing 
from a pi to a pi-L always increases harmonic suppression. 
It depends on the network Q, the layout, and even the load 
impedance.
