Just picked up a Sequoia saddle and would like the option of using a pulley on the bridge but as you know it comes with webbing not rope. Didn't have much luck with the search engine so here is the question: Has anyone found and used a factory made rope bridge from another saddle that is comperable in length? I have not yet used the ring which is available either so any input on friction or wear pros and cons based on personal experience would be appreciated.
