Ooo guitar is a great example I wish I would have thought of that one. And the equilibrium idea is exactly what I was thinking about, it seemed to me it would be way easier to break an unstrung frame on the ground by bouncing it than a strung one for sure.
I appreciate all of the input here and will definitely be going low.
