I prefer a lock on for placement but ladders for safety. I have move to using only ladders but may use loc ons again with life lines. I have had one break and a buddy had one break. Mine was the steal cable holding the platform the other was a year old strap. I have never had a ladder stand fail but I have been close with one that didn’t have pins in the ladder sections. Climbed it in the dark and about 5 feet up I realized the ladder had separated. Luckily the ladder was about a foot in he dirt and didn’t totally fall over.
