Marlinspikes. I first saw the idea of a marlinspike presented on GrizzlyAdams videos. That seemed to me like a very logical and practical way to hitch the suspension to the tree slings. But I did some searches and found almost very few thread even mentioning using marlinspikes and (wood) toggles (maybe I just did the search wrong, but regardless there were few hits).
So what are the pros and cons of using a marlinspike to join these parts? Who does and does not and why (or why not)?
