The original setup was bare copper with no solder.  In that case, I believe
that tinning just the very end with solder (so the solder ends while still
under the screw) will provide a slightly better connection.  But letting the
solder extend farther up the wire (which is difficult not to do) creates a
stress point that is more likely to break the wire over time (and
vibration).

However, if memory serves, the wires in Dan's kit already have the strands
individually tinned (silver color rather than dirty penny color).  In that
case, I believe that adding solder is a bad idea.
