Can I use just half the biwire?

@ scott_w

I also agree with lowrider57

Something no one has mentioned, will the un-terminated ends of the bi-wire cable work as an antenna and introduce RF back into the output of the amplifier?

You might want to send a PM to almarg and ask for his thoughts.

Same question was asked last week - most binding posts will accept two bananas one in the bare wire hole, one in the banana hole

Thanks everyone! Good info. 

Rodman, understand your comment and knew it.  I was just trying to say it in layman's terms to give scott a better idea to build from.  Keep the biwires together.  You paid for all that wire.  Use it!
