I am confused about the degree of flexibility that you are looking for. Are you talking about cables that are so flexible you could use them to for shoelaces (pretty much like the cheapies that come with every piece of electronic equipment that has an RCA jack)? Or are you concerned that the cables you described cannot make the bend from component A to component B if stacked upon one another?. If its the later, the premium Monoprice RG-6 based cables can certainly fold in half (with a bulged loop at the closed end).
