Assuming the current filtering run (2.59B uniques, target_density=140) succeeds, I will probably start LA afterward. The size of the relations file is becoming the issue at this point.

Not sure about the target; something in the 90M to 100M range would be nice. I'm also running up against the sheer size of the relations file, which is now about 200GB even gzip'ed.
