I broke mine one time. I contacted Hennessey and Tom told me the length. I then spliced a piece of line to both ends of the break (I of course had to cut some of the original line so I could splice a short section of new rope). I used a Double Sheet (Becket) Bend knot to tie each end of the splice to the ridge line. That will be the last place the ridgeline will ever break again. I found the knot in an old Blue Jacket Manual. I'm not a knot tier so others on this forum must help if you ask me how to make the knot again.
