Solid wire vs Stranded?

MIL-W-22759/16

This is my favorite wire to work with. When I make twisted pair, it stays tight. The ETFE insulation is very heat tolerant. It is mechanically tough, and wires stay where they are routed. The insulation is thin yet rated to 600Vrms. The only drawback is that you will need to upgrade your wire strippers (unless you are a glutton for punishment).
