George L's along with the Evidence monorail are exceptionally discreet and used by top notch cats. Monorail is pretty inflexible, so won't take kindly to many moves.
The Lava cable with non-solder ends is awesome stuff. I wound 30 ft of the stuff with umpteen ends for a board I rigged up; it's awesome. Easy to use, great price, great quality.
Peace,
