I had a Flexi KS-P-A-M-L-I-N-K- break too, after bailing out while buggying. The threading sewing the loop at the end gave out. The bungee did not break . I went to Home Depot and bought an appropriately sized aluminum cable ferrule and crimped it on to form a loop on the end of the bungee that was once sewn into a loop. You'll need to use a swaging tool to crimp it down but it works fine. Looks pretty ghetto, but hey--I am "Pokitetrash". Cost about $1.00 and it's still flying after almost a year.

The cord broke on mine...twice (so far) seems to break in something over 20, maybe 25 or so...I know I couldn't hold it, thats why I let go
