I have seen the long string register about the same as braced, I have tested this just to see,,
when comparing braced to braced,, I see a difference, my scale will register a difference,, I have not tried comparingf something extreme,, like for example,, 2 inches of brace compared to 10 inches of brace, I think that would be interesting,,well its all interesting to me,,
you know your life is a bit boring when brace hieghts are really interesting to you,,
