I untie mine, reloop them & make a hangsman's noose knot on both ends of my hangers. I don't trust the way they tie them because I had one come apart & ruin my Nextlight Mega. Had a ratchet stay open once & wouldn't click to stay in position. I too use 2 hangers in each spot I'd normally use 1 when hanging heavy stuff. I don't leave any slack though. My Light must be 40-lbs. so I've also added a bunch of extra hanging bars which has this tent solid as a rock.
i also noted there are several builders providing only two attachment points. once a rig gets that large, i'd consider 4 attachment points to be a given. most builders are a serious fail on this.
