I have the same MM safety spreader harness bar. Overall I like the harness (Pro Mesh), but I question the 'safety' feature. While on land I pulled the quick release pin the other day. It took me at least 30 seconds to get the pin released and I had to FIGHT to get it released... I could have undone the entire harness and climbed out in less time with less effort! One other thing, once the pin has been pulled you have to take the entire harness off and fight to reassemble the safety hook assembly, which was another major ordeal to get it back together. On the flip side, the hook has a nice keeper finger (not shown in the above pic) on it which allows the dog bone to slide off easily so I'm not sure why you'd need the 'quick' release anyway. Other than the POS quick release feature, I really like the harness.
