It's a good idea to get MindGuard on your computer now so that its ready for when you really need it.

Seriously, though, if that's possible, having all the conductors of a circuit in the same cable pretty much eliminates rfi interference. (That's what we're talking about, right?) To do more, bx is better. Try using a volt tick on bx. I've also noticed that dirty, wet loomex doesn't trigger a volt tick either. Maybe you can do something with that.
