A better / stronger shock cord or alternative?

[wiznut]

I went offshore to the rigs to chase AJ a couple weeks ago and shot a fairly nice one. It went one way around a cross member and I went the other to tie it off and finish it. After getting it on the stringer and putting my gun back together, I found a weak link in my setup... the nylon of the shock cord had just about been cut through on the crossmember and the bungie looked like a barracuda used it as a chew toy.

So my question is then.... is there a better shock cord solution for hunting rigs? I've got steel cable shooting line and slip tip, but the shock cord seems like a very weak link compared to the rest of the rigging.
