Magic
I have several different bags for my Hassy kit, and which bag I use depends on where I am going and what I am carrying, but most recently I have been using a Tamrac Velocity (7X?) sling pack most often. I have a couple of the MAP lens cases which can attach to the outside of the bag if the load is a bit larger, or go inside if I am not carrying as much. I routinely pack the bag with the body (503CX) two backs, a set of filters, the 80mm and 150mm lenses and 6-10 rolls of film. By rearranging I can add the flash, or a 50mm lens, or both. Lots of versatility, but not the prettiest bag.
