Nightmare Mike,

 >From my and other's experience, especially with small diameter wire, just
position the wire spool vertically and let the wire feed vertically,
unwinding off the end of the roll.  The twist imparted to the wire is of no
consequence, and you eliminate the inertia of the wire spool and its
tendency to break the wire.  Just be sure the edge of the wire spool is
smooth - cover it with tape if necessary.
