Application of synthetic rigging

[Auspicious]

On another forum, a discussion has wandered into the use of synthetic line for standing rigging and questions I can't confidently answer.

1. What issues has experience raised with sharp edges? (knives, broken bits, vandalism)

2. How well do they hold up to rope burn and chafe? How often does the jib sheet rapidly "slice" past a single spot on the standing rig while coming about in a stiff breeze?
