Opis:
Does a purcell prusik shock absorb enough as a personal lanyard to prevent an ascender from desheathing a climbing rope if you were to take a short fall while passing an obstacle? A little is the answer but 1/2' ropes are so burly that they won't desheath even with a static sling in our tests. However, your spine may not appreciate 5kN+ so just don't fall.
