Recommendations for surround speaker cable?

I'm running Nordost Blue Heaven ver.2 to my main speakers. I need to buy new speaker cables to the surrounds. It will need to run under carpeting and then through walls. I need 100 feet, and running the Blue Heaven that far would cost as much as a Porsche. I've got Snell speakers all around -- mains, center, sub and surrounds.

Any recommendations? Thanks, everyone.
