I cannot imagine the rope coming out of the Bone without asking it to. The links that swing aside to load the unit actually snap shut and lock into place, which means they bear load on both sides...yes, one side has a cut out to allow it to open, which in effect will reduce the strength on that side. With proper use (like ANY climbing system requires), I do not see any flaws with the unit. The only thing that could be improved upon is a design that incorporates slick pins like the beloved Rope Runner. This would mean using something other that chain links to create the moving friction components, but the chain is fine in my mind. Use it properly and you're good to go.
