..but if you are basically after big, loud sparks rather than precise
waveforms, inductors are much more hassle - the inductance has to be
pretty high to avoid the DC path becoming significant and sapping the
energy after the initial firing, and also think about the standoff
voltage the windings would have to sustain. Resisters will be much
easier.
