Option 5: You can strip enough insulation off your cables to allow bridging the posts with a continuous length of wire, thereby eliminating separate jumpers altogether, and the additional lossy connection points you'd have with them. This makes for the least connection points and lowest possible impedance. As a bonus, it will cost you nothing.
