After looking at this Golem buckle a little more I am not sure it would work as well as a cam buckle in this application more secure but harder to use. From my perspective, the purpose of a shoulder release on a harness that tightens the shoulder by pulling the belly-band is for easy doffing. This buckle looks like it requires two hands to release and would be difficult to do in the water by feel wearing gloves. One hand operation is really desirable, especially in high currents where you need one hand for a drift line.
