I've ruined a few deans with sparking on HV setups, with bullets you can do one at a time and be quick though, I can usually get it without a spark.. I was thinking of following Biran's calcs for a no spark resistor though...
Yeah, that's a bad idea. We don't recommend it.
The calculator also is WAY off for charge times -- you don't EVER need to charge a capacitor that slowly. A .1 ohm resistor (yes 1/10 ohm) is enough to keep the spark from happening.
The only thing that suffers from the spark is the connectors.

And they are cheap enough and simple enouigh to replace when they wear down.
