I don't use bungee cords for anything that is important. I have seen too many of them along side the road.

I generally don't have tie down issues, due to owning an Xtrcycle, when I do have issues where something needs to be tied down, I usually use the camlock straps that Xtracycle sells. If I still need more I have a hank of 550 paracord that I can use.
