I hear yah, Mitch.
Once I get everything dressed and supported with cable clamps every so many inches and it looks really spiffy and will never flop around, THAT will be when I decide I need another wire for something I never thought of. It's always that way......
And the more time you take to dress things off and wrap conduit ends with tape to seal everything up, the sooner you'll have to take it all apart to run that one more friggin wire.
