I am all ears on this, but I had an idea. What if you took the goldenrod, or even a piece of piano wire, going through a piece of ''rubber'' hose that had a tie wrap around it to provide just enough friction to hold the spring tension? Maybe just put a clamp around the outer jacket of the goldenrod? I haven't done it yet, but it is an idea that certainly won't cost much to try anyway.
Good idea!!
This is what I had
Just a piece of standard blue and yellow nyrod
