Stranded or Solid?

[Anonymous]

For power on my layout I only run the hotlead to a dozen lockons. It's on an old ping pong table. Common (ground) is tied to an alligator clip which I clip onto an outer rail at the end of a siding. Grounds the whole layout and saves lots of searching for double conductor.
Stranded is great for (re)wiring accessories and their controllers. Won't fight like solid wire when you're soldering a connection that needs four hands.
