i solder, and occasionally crimp when it hard to get a soldering iron into place, or i cant find my solder :P strip the wires, twist em together, solder, heatshrink. but as with all joins of any type make sure its got sum "give" in the cable, coz even if its the best crimp in the world, if its got no give, it will eventually either break the wires in the cable or cum loose.
