If you are discharging your caps into a thin wire to produce long, loud
discharges, then it will depend on the nature of the wire as to which caps
will work the best.


For this application, getting perilously OT, higher is better, voltage wise. In this application you want high di/dt (so the wire explodes rather than melts). Since V=Ldi/dt, and L is pretty much fixed by the load (and the cap), high V gives you high di/dt.

A few kJ at 20 kV works very nice for 1 meter long wires with a couple of meters of connecting buswork.
