Jeremy,

I've run coils up to about 40kV input or so and had no problems with
insulation or system behaviour.  I also didn't see any benefit, although
theoretically there may sometimes be a benefit.  Mostly I think folks
usually use traditional designs and voltages around 12 to 15kV for
medium and large coils.  Greg Leyh's large Electrum coil uses about
40kV I think.
