If you'll notice, I did see that. It just took a post or two.

Regarding the complexity, it's not that complex. If you're already going to wrap around the winch drum, you could drill a small hole all the way through, run the string through that, wrap a few more times in the same direction, and
then attach it at the same distance from the pivot (or a shorter distance, but you'll get some slack that way). If you're unsure, you can cut the string extra long and adjust as needed.
