RE: Capacitor Orientation

You can apply a signal to a cap and if you have a scope you can put the probe on the surface of the cap. If you apply the signal to one lead of the cap and then the other the scope will show one lead connection has a stronger signal on the cap surface - that's the one connected to the outer foil or plate (it's right under the surface so the signal is stronger than the other which is further away).

The Sonicap people should be able to tell you which lead is connected to the outer foil, try giving them a shout.

Except at RF frequencies the shielding effect is a non-issue in my experience. But as the old saying goes "a little chicken soup can't hurt", so try it if you want since it costs nothing. It may help if you have strong RF fields in the vicinity of your gear.
