Just looking for an answer to a question that maybe I'm over-thinking, but if one has to leave a rappel anchor, or if an existing anchor looks sketchy, which is a better material to leave behind- 1in webbing or cordellette (say 6mm)? I'm not so much concerned with which will get me down safely, I have confidence either one would, but for those who come after me, I might as well leave the best thing should someone else need it. Thus, I'm specifically looking for which one wears better in the long run, which one will visibly show wear better (to help others determine if it's safe-- don't want something to look fine but really it's crap), and if it could be a factor, which one would be better for the environment, though I know leaving anything behind is not exactly good. Any opinions/insight is appreciated! Thanks!
