I was under the impression that attached sparks degraded the 
quenching because of the impedance mismatch and resulting reflections.
Are you saying that certain lengths of attached sparks, or perhaps
non-hard grounded attached sparks give the proper loading.  I'm not
too clear on all this it would seem.  I'd appreciate it if you could spell
out the conditions for proper loading.  Do these attached sparks have to
be the permanently attached (short) types?      Thanks.
