Yes Chris. It's all line and tubing. The big problem is, it's very bad about coming unhooked. When you take the load off, the line trys to assume a circular shape.

I made one once by soaking the line in epoxy, covering it in heat shrink, laying out the shape, heating the heat shrink, and letting it dry. It was a simple figure 8 shaped loop with one end bigger than the other It worked ok.

Then I found out if you spiral cut tubing and put than on your dogbones, it does not hurt your teeth and it works even better.

The little metal thing on Marstrom works pretty well and has not hurt me yet. Do think your wife woulkd notice if you stole hers?
