Gland you weren't hurt, MB.
However, calling tree climb line dynamic is a bit of a misnomer. If you compare stretch characteristics of static kernmantle, you will see that the stretch is appx double that of 12 or 16 strand tree climb line. Our lines can easily transfer way over the acceptable Kn forces to a falling body, say in a full factor 2 fall of 16 feet, such as UIAA testing standards require a dynamic rock climb line to meet, These true dynamic lines stretch up to 70% at break, ours maybe 15-20, I'm not sure.
Full static line would be the high tech fiber lines, like Spectra and Kevlar, which stretch 3-5% at break.
Thus, my point, don't fall on tree climb line, you can get hurt!
