2-to-1 resonant orbit better than Lagrangian points?

I was reading Heppenheimer's book from the late '70s on space colonization. He mentions that although L4/L5 were originally chosen by O'Neill, later analysis showed that a "2-to-1 resonant orbit" with perigee 100,000 miles and apogee 200,000 miles was preferred. The reason was that the transfer delta-V from the L2 collection point to the 2-to-1 resonant orbit was much more favorable than the transfer energy to the Lagrangian points.

Is this still the scientific consensus regarding the location for a production facility based on a lunar resource/mass driver scenario? If you read Heppeheimer's subsequent book "Toward Distant Suns" (1979, Stackpole Books, ISBN: 0-449-90035-5), you'll see he says that orbit was latersupplanted by a "rather dull" circular orbit, about half-way to lunar orbit. That's the orbit I'm usually referring to whenever I say HEO. Past a certain point, O'Neill said to please consider "L-5" as shorthand for "whatever orbit they finally settle on as the best".
