You guys better keep it down. The lawyers are gonna find out about this, there's going to be a class action suit, and the price of bungees is going to triple and I won't be finding so many of them littering the roadside any more.
I'm just a spectator in this discussion. My solution to the strapping down the load problem was to eliminate the load that needed to be strapped down. I now only carry a rolled up CCF pad on top of the rack, along with the occasional post office delivery, and a short bungee (that I found on the side of the road) works fine for that duty.
