Thanks for the tip on the groundthrows, Ed. I think I'll try it on my new layout. After trying several things, I am a fan of the groundthrow. I tried a fancy electrical panel with mini pushbuttons wired in red-green pairs, but was always having to orient myself on the panel and determine which button to press. With the groundthrow, you can paint one side and immediately tell which way the switch is aligned, even from a distance.
