Nothing new or cosmic here, I'm sure, but I've progressed from kit supplied plastic tow cables, to twisted lamp cord replacement cables, to a current technique of taking bicycle cable wire for the tow cable and electrical wire insulation for the eyelet connector.

Bicycle cables have more twists per inch and are thicker than picture hanging wire and therefore look more the part. (IMHO anyway)
Let me know what you think.
