Just a thought, you don't need to have the bi-wire ends dangling in the air if they are spades. Just connect one set from the bottom and one end from the top to form a "ring".
As an aside, depending on your listening preferences, you may want to tune the response of the speakers as even different ZU cables will result in a slightly different presentation.
If it were me, I would try 3-4 cables within your budget range, keep the one that sounds the best, and return the others.
