Bi wire with one set of speaker terminals?

It also works well where you can use Silver for the top/mids( highs and mids ) and copper for the bottom ( lows ),from the same manufacturer..I did it years ago using Audioquest Argent for the highs and Midnight for the lows..Great combination and to me this is the best way to bi-wire where you use can both silver and copper under the best situation.......

Use a jumper cable that is at least equal in quality to the SC's.

Samhar is correct. The jumper is as critical as the cables.
