This isn't a classified (didn't know where else to post it), just a suggestion. If you take trips and have been using bungee cords, you might want to check out Rok Straps instead. Nothing to scratch up anything on the bike or luggage rack, fully adjustable to fit virtually all luggage and cinch a bag down tighter if needed, different sizes and colors. The ends have loops and a clip to attach to the other ones with a clip. No brainer. I've been using them for a couple of years and they work beautifully, especially after once scratching a bike with bungees because the rubber coating on the metal hook had worn through. Rok Straps are cheap too (under $20). You can buy them at almost any moto website or Amazon. Worth checking out.
