Ah, that's the beauty of star-quad cables. You can try it all three ways! The Canare 4S11 is nice stuff. That's what I'm switching to. I only have my mains done now. I'm waiting to do my center and surrounds until I get a TV, which may be a while. I'm just wiring it shotgun (single wired) to my speakers, which have posts for bi-wiring/amping. Like others have said, there is essentially no reason to bi-wire. But, if you really want to try it, then by all means do so. Just use bare wire termination until you figure out how you want to wire it, then put the ends on. As far as the ends, I would highly recommend the locking banana plugs, also from BJC. A bit more expensive, but they have the grip of death and are oh so nice.
I say go ahead and get the Canare wire. It will work for any configuration you outlined, plus the 4S11 is a great cable, so you can't lose! How often does that happen?
Here's a quick pic of one of the cables I made up, just to give you an idea. They will look really sweet once they are wrapped with Techflex, which others have done and posted pictures on the forums.
