differential will be hellacious if you don't.)

I've never had to disconnect coaxes but if you do you want to cap your
connectors with shorting caps or use a grounding switch... I trust the
quality gas tubes I use more than I trust my memory to handle the

Woah, braid will explosively disintegrate during a strike.  You wan't
