Flying Wires Vibration

[pulsar747n]

I have noticed that the flying wires started to vibrate during a climbing turn to the right or to the left. Usually the right flying wires vibrate on a climbing turn to the left and vice verse. The vibration stops when I level off. This did not happen earlier on.
So the question is: Do flying wires stretch with age and use and do I just tighten them enough until the vibration stops? Or is there something going on inside the wings?
I do not have a tensiometer and just used a fish scale to set up my wings. Any ideas? Thanks!
