Update: Fixed that wild load swing by tweaking the taglines.
Took me a while to see the wind was catching the sling wrong.

You said the wind was catching the sling wrong, which makes sense. I bet the sling's shape plays a big part too, not just the taglines. A flat sling will catch more air than a rounded one.

Watching crane operations downtown, the flat slings always billow like sails in the wind. That totally lines up with your point about shape making a bigger difference than just the taglines. It's a real pain to manage when the gusts pick up, lol.

Yeah, that's it exactly. We had a huge roll of plastic sheeting do the same thing on a jobsite last spring. Wasn't even that windy, but it got under the flat face and turned the whole thing into a giant, flapping airfoil. Took three of us to wrestle it down and roll it tight. You can have all the tie-downs in the world, but if the shape itself catches the breeze, you're just fighting a losing battle.

Reminds me of a time we were moving a big fiberglass panel. It was maybe eight feet square, and a light breeze got behind it like a sail. The tagline guy was just along for the ride, getting yanked off his feet until we could turn the thing edge-on to the wind.
