Higher grid resonance is more desirabler since it increases vhf
stability. To see if strapping to ground is really the "best bet", use a
(real) dipmeter to compare grid resonance with 3 x 200pF = 600pF to
ground (Heath stock) vs. resonance with direct strapping to ground.
One of the more laughable old wives' tales in ham radio is the assumption
that heavy strap has zero inductance.
