Whom to invite to a Powercord shootout party

I have ordered 2 of the new PS Audio P5 conditioners and plan to use one each for my Monoblocks (each one on a different circuit). While I upgrade powersource, I will also need 4 new cords; 2x for P5 into the wall, and 2x between Mono's and P5. I am planning to do an in house shootout between what I currently have and one or two cords I am hoping to pick up on A'gon reasonably priced

What I have in house now are:

JP Cables Maximum Gold (very heavy gauge, but cheap cable)
PS Audio AC-12
Gutwire B12
I also just bought one Synergistic Research Precision AC

I am willing to buy one more contender in the $500 used price range for the shootout. Whichever cable wins I'll need to get four of.

Any recommendation for a cable in this price range for a high current application? It has to be a cable that is easy to buy and sell with minimal loss - so not the real esoteric stuff.
