Brian, I really like the DNZ rig you are recommending. If they offered an option with two-bolts on each side of the ring - I'd be all over this product! Its rigidity would be perfect. It seems 2 or 3 bolts would help prevent the rig from coming loose - especially on aluminum rings that can't be torqued quite as much as the steel rings can be. It seems this might be the weakest link in my setup. Am I incorrect?
