I just went thru the same thing. I moved my amps to the side of the room, where before they had been between the speakers. I needed much longer cables, so I went with Signal Cables Ultra - a 22 ft one and a 14 ft one so that I wouldn't end up with a bunch of excess cable piled up on the floor for my right speaker.
You might want to consider the asymmetric length option, even if it means that if you resell, you'll probably have to sell them as singles.
