There are a lot of opinions. I have used 1" dia 6" long 15 turn air chokes
of wire stiff enough to stand alone 16ga. I now use two 1K 50W wire wound
resistors (256 uH Q=.oo5) as RF chokes, one per lead. I have also wound 20T
of high voltage wire on a TV deflection coil ferrite core potted with clear
RTV rubber. All work well. I now use these in a "T" filter in each lead with
434 pf shunt capacitor (9  3300uf in series) as protection and a noise
filter to my spark gap.
