Terry & Marco,

Just a note regarding my experimental observations that for a given bang
"size", my DC ARSG twin TC streamer length stopped growing significantly
above the range of 240 to 300 BPS.  Going up to 700 BPS produces thicker and
more impressive streamers, but they aren't noticibly longer.  Streamers were
in the five foot range.  Marco, we appreciate your careful measurements and
you taking the time to share them with us.

Terry, if you switch to DC resonant charging, running at any BPS you wish is
a very non-daunting task indeed!

Marco, if you switch to DC resonant charging using a SPDT spark gap (i.e.
add a second set of stationary gaps to your RSG, charge the primary cap
through one set of gaps, discharge it into the primary coil through the
other set of gaps), then you can reduce your BPS to be as slow as you wish
without power arcing or other premature discharge effects.
