Building Balanced XLR Cables

I am building XLR cables using 3 conductor + shield wire. Typically I would solder the shield to ground, 1 wire to hot, and 1 wire to cold. Should I connect the 3rd wire to the ground (shield), use the 3rd wire as the ground (not use the shield at all), or not use the 3rd wire at all? Thanks in advance.

Then tvad they are not balanced. Pin 1 has a shorting contact to the XLR housing. There is no forth ground. The proper wire is three conductor. The forth wire is there I believe for powered microphones. Any interconnect without a proper shield is asking for it.
You hook the shield up to pin one and leave the third wire unused at both ends. You use a floating shield in power cables. You are floating it to prevent ground loops.
