Two types of wire that are better at stretch  are:

- # 12 submersible well wire; it is hard drawn solid copper.

- #12 jacketed solid copperweld.  I use this stuff for long beverages and
tension it with a come-along so it is almost  guitar string tight. Even
trees coming down wont stretch it. 

Walking the wires regularly is excellent advice since trees laying on the
wire can cause pattern distortion.
