Are you suggesting not using a dedicated RF ground and connecting the 
points you mentioned only to the mains ground?  For small mini coils, this 
may be adequate, but for anything with a medium to large power supply (like 
what Dr Resonance was talking about), one really should use a dedicated RF 
ground.

Oh yes, I am duty-bound to mention that Ed Wingate's big pig-fed magnifier 
IS connected to the mains ground.  But I think being in a dedicated coiling 
structure with a limited extent of mains cabling, and probably it's own 
ground rod and distribution panel, separate from the house, make that 
different than typical household situations.

RC filters, MOV's, and safety gaps are there solely to protect the 
NST.  They do nothing to diminish the transients headed out on the mains.
