Please god, no more zip ties. Use double sided Velcro strap. You can buy it in a roll and cut to length. Reuse it all you want. Join multiple shorter lengths to make a longer one. Just please don't make me cut another god damn zip tie off a bundled cord. I deal with enough zip tie bondage fetishists at work.
Back many years when I was touring with bands, at the end of the night you'd see all the lighting crew walking around the stage coiling the long cables, with one end trailing after them, to make sure the twists were correct. That was much more useful than generic over-under for all cables.
over-under has its place, but I don't use it everywhere.
