I'm using the same stuff but just the single pair version. Good wire. It is amazing how much time and effort was and will be spent to just move the wires about 16 inches tops.

For the record, I soldered and added heat shrink to each connection for maximum effectiveness. I not only put shrink wrap on each individual wire, but then a larger piece over the entire section, including the white outer casing on both ends. Should be good for as long as we own this house and beyond.
