I'm using a switch mode boost converter with a 9VDC input, so I think i'm good on that count. The high voltage is scary enough, I don't think I'd want to run the nixies directly from mains :/. I think I'll go with the 10k unless anyone thinks I should be more conservative and use a 15k. If anyone can clear up the point that GastonP made about the duty cycle, that would be awesome.
