If you don't like comebacks, crimp it properly with the correct tool,
and *do not* solder. Solder makes a crimp connection brittle, and
vibration makes brittle things crack. Soldering a crimp connector is a
widespread practice, but it makes the connection less reliable, not
more, as long as the connector is sized correctly for the wire and
crimped with the correct tool.
