I'm currently using some of their 15ft VELOCITY™ SPEAKER INTERCONNECT 12AWG wire and it is perfect. Really you couldn't go wrong with their wires. The wires come cased in a dark black/purple sleeve that help keep everything in line. It wouldn't hurt them to give maybe another inch between the rubber sleeve and the exposed wire so you can make connections that are not super close, but it's really not that big of an issue.
I would get it today because tomorrow you lose the extra 5% off.
