The only real good terminal for electrostatic shielding with standard 
coils is the torus.  It is the shape of choice for the lowest electrode 
nearest the system coil.  Anything on top of that can be tried for effect 
but the first item just has to be a toroid.  I could only imagine one 
better shape and that would be a highly oblate spheroid that was 
flattened like a mushroom.  Try and price such a custom item out, and I 
think that toroids would remain the terminal of choice.
