I have replaced it with the original Big Agnes shock cord, it works well. One thing I have to mention is that the cord size is slightly thinner than the original one. 18 feet is exactly or more than enough to replace the shock cord as long as you do not make any mistakes. The price is cheap and worth the replacement yourself as long as you label each pole prior to taking out the old shock cord.
