After years of working at Remote Audio and wiring every type of cable/connector you can imagine, there is another factor to consider beside the difficulty factor and that is the condition of the cable. Example, someone mentioned wiring Sankens. Due to the
oxygenation of the wire on older mics, you cant repair it without replacing the entire cable. The wire (which turns greens) will just fall apart in your hand, so in this case you spend more time trying to get it to take solder, where you save time by replacing the complete cable and being done with it. This also applies to all types of cables. Oxygenation can be a big problem so always check the cable to make sure its worth repairing.
