Recommended Ribbon Speaker Cables

Here's the story. I have to run about 20 ft pair Bi-wire speaker cable and it needs to go under carpet (if at all possible). Looking for help from Audiogoners on what the best way to go in about the $350 or less range.
Are QED Silver Anniversery Bi-wires good for this setup?

Thanks in advance, jim
