I use 14lb mono... The problem is everytime we catch a good one, The wire gets stratened out. When you bend it back into shape it fatigues. Just like bending a coat hanger back and forth. The thin wire will not take this abuse near as long as the thicker wire. Once the wire breaks, you loose all the hard work of buying components,pouring,priming,painting, clearcoating,tying,blade and swiveling, and trailer hooking. So I try and build a bait that will catch as many fish as possible before it's junk. I guess you could always make a loop at the head and use it as a jig for a while.
