I wouldn't get too caught up in all the cable hullaballoo. To keep it simple, I'd suggest a set of the WBT power bridges to link the high and low binding posts, and then run a pair of "single-wired" (one pair of connectors on each end) cables. I prefer the WBT midline banana plugs for this purpose.
As far as the type of cable, I really think 12 AWG copper "zip cord", which you can get at your local home supply store is fine. Should be about 50 cents a foot, and sounds great. If you can find larger gauge, then that would be even better.
