Robi,
Spectra threaded inside clear plastic tube and tied in bowline works great in place of dog-bone. Even though the spectra easilly takes the load it will eventually fail through fatigue at the load point from the trap hook.
Just make sure you replace the spectra annually and you should be OK.

Phill

There is no such thing as a quick fix and I've never had free lunch!
