Derek- perhaps when you have the time and actually read the article, you will notice that they did test static rope (see page 14) and elude to their conclusions many times. Plus they tested the Petzl tails which are static as well. I guess that means dynamic is no longer "standard practice". I guess I do not know what your definition of "standard practice" is since many cavers I know do not use dynamic, and a certain cave rescue organization that I am involved with does not require a dynamic tail.
Of course you would trust 40' of dynamic rope- that is because at that length the rope is able to do its job and stretch the needed amount, but at 2 feet it cannot! I guess that we disagree as to how you are using your tail. You call it fall protection and I call it misunderstanding fall prevention.
I trust 40' of dynamic rope to catch a 20' leader fall just the same as I trust a 2' dynamic cowstail to catch a 1' fall in a cave.
