Du-Bro's is ok, but used as intended has a high potential to fail, especially the 2-56. Du-Bro uses plastic coated braded wire that you thread through a small drilled hole in a threaded clevis connector. The sharp edges of the connector will cut the cable over time.

I like the Kevlar set-up through an I-bolt. Here is a picture of both. The Kevlar set-up came from Don's Hobby shop in Salina Kansas. He advertises in most of the RC mags.
