I didn't even tried anything other then Dubro's set-up. This system was the first pull/pull I installed a few years back, and have had -0- problem with it, as well as every other DB set I've used, and it's only about 7$ to 8$ a set-up. I might want to check into the kevlar also though.
Another plus on kevlar other than it being the strongest available, is it's non-conductive, non-metallic. A bit of added insurance there it seems.
