Can you provide any tips on efficient use of cords and hooks for securing items to a Brompton rack? On occasions you may need to carry this or that on the rack and I found that I am not that good in securing the items to the rack. Too often found that I nearly lost my stuff and I hardly ever get to my destination without stopping to readjust. Now the rack has hooks and these evolved with rack design over time, so people must find these useful. I started using them and my packing got a tad better but I still feel that I am not there where I should be. Sure strategies must differ with size and type of items, but I am at a loss no matter what I am to carry. Any help?
