I fold the line nearly in half, leaving one end about 3 feet longer than the other. Then I repeatedly fold the line in half keeping the short end just a bit longer than the bundle. So I end up with a 3' piece of line and the other end just barely sticking out of the the bundle. I then wrap the 3' end around the bundle and secure it.

Now as long as I keep both ends somewhat together and don't allow either end to get into the bundle, the line will not tangle.

I just unwrap the 3' piece and holding onto both ends, I drop the bundle. It might tangle a small amount but usually a quick shake will clear the tangle.

Works surprisingly well.
