Oh wow, that's not cool. That's the same one that I used to use. I went back to my 3 bungee cords holding my bag because a few times while taking tight turns with my trike, my bag fell off the side of the rear rack and was hanging there. Luckly it never fell completely off, but after going back to using 3 bungee cords in a criss-cross pattern, it hasn't slid since.
