Tour Master makes a good roll bag that has the bungee cords attached to the bottom of the bag, I used this one for the GA Rally, even comes with a rain cover and made a good back support for the trip down and back, 5 days.
I have the RiverRoad zip off bags, I've been told by others on this site that the real test is if they will hold a case of beer. Well each bag holds 2 sixpacks, guess they qualify. These look like leather but are synthetic something so they are water resistant and you don't have to treat them with junk like leather bags. The saddlebags came from Bikebandit.com the Tourmaster bag you can get from any on-line or local accessories stores. Happy touring, don't get the bag too big because your wife will think its OK to bring her whole wardrobe, hair dryers, curling irons. You get the IDEA.
