A mentor of mine did airplane wiring during WW II. They initially used cable lacing that was likely similar to your Collins method. What they found was a machine gun bullet that penetrated the airframe caused more damage due to the laced cable bundles. At some point the changed to just laying the cables in the wiring trays.
(It could have been Korea instead of WW II, but he is SK so I cannot ask him to refresh my memory.).
