I strongly second Mouse’s recommendation (and to you too, Adrian).
Suddenly placing a large charge anyplace on your ground plane (the pipe is as
good a choice as I can think of, but ….) could invert diodes, back-bias
transistors, etc. etc. and it’s just so easy to avoid by having a large
high-voltage resistor in series with your clip. No loud snap, no pyrotechnics,
your hand won’t jump in involuntary reaction to the loud snap - it’s just a
much more controlled and gentle effect on the system.
I have not done it myself (either way) but have seen it done, and it
works well. Resistors are really cheap insurance in this context.
