A nice tight wire nut connection has always worked for me even with a
mixture of solid and stranded wires and I've taken the connections apart
several times afterward to make sure there was good contact area. I agree
that pre-twisting the solids helps. In earlier days, I just soldered the
bundle and put a wire nut over the top for insulation.
