I can't see these things breaking either way. Biggest load is gonna be on the pivot pin IMO, in bending from the cantilevered LCA. Those pivots are made from some kind of special steel for the application, but I can't remember what he called it.

Edit: "stressless metal" for the pivot pins, whatever that is. And the tubes are 4130, not heat treated.
