I'll let ya get by with crimp connectors, AND heats-hrink. The problem with scotch-locks is it is very easy to chop the individual wires off! then you only have a few strands to conduct the current. Then the weight and shape of the scotch-lock starts to bounce however minutely as you go down the road breaking the surviving strands. Also the shell of a scotch-lock is a perfect trap for water or moisture, the alum blade vs the copper wire and electrolysis starts. The advantage to the crimp connector is twofold; the bounce is spread out away from the conductor wires and it is possible to slide heat-shrink to seal the connection from moister.
