I have also had back check wires bend very easy. However, I don't think the 
wire was moving in the doublet. (I figured out what it is, although I still 
have never heard of that piece of wood called that before). I also don't 
think it was wire fatigue. I just think it is a weaker wire material. Why 
Steinway choose to use that I don't know.
