Bi-wire: is it worth it?

My speakers are set up for bi-wiring and my cables are bi-wired Kimber 8PR banana plugs. If I wanted to compare bi-wire to regular (single) as this point, what do I do?

Yes, I have the original metal jumpers, but some think they degrade the sound and custom jumpers are needed. If I get custom jumpers, what brand?

And ... lastly, what do I do with the extra set of cable leads? Tape over the banana leads and fold them back?

I bet the whole quixotic exercise will be one of futility, but I'm game to try.

Grinnell, please explain "use a 3/5 configuration."

Tls49 ... yes I have thinking about doing just what you said, which is to use heavy gauge wire to act as a "hot-wire" jumper between the 2 sets of terminals. If it sounds better, I'll take it another step further -- maybe buy quality jumpers and single terminal speaker cables. Or, I could just buy jumpers with spade-ends and live with my bi-wire cables.
