Hi, Thinking of just getting some mains cable for my speakers, but was just wondering how flexible the stuff is? I will need to be running it around the room to the rears, so will need to bend around corners and possibly over door frames. Also, is it easy to fix in place when running it to the speakers? What do people generally use to keep their cable tight against the wall? I am a stickler for a neat set-up! Thanks Mark.
