You might consider what jnorman said and hand shoot an older (beat) Graphic by the sports finder. No darkcloth, and even if you have the time to GG compose you'll have a hood. A handheld meter amd some quickloads will be light with say a 135mm Sironar S. Add a real light tripod like a Velbon Chaser EFL-4(A) 3.5lbs, 12# load capacity and 20" collasped. A small Giotto MH1001 at 1# will hold anything to 16- 17# in weight. It will all fit (maybe not tripod) in a common backpack with room left over for lunch and weather gear. A 6x9 Graphic with rollfilm would be my second choice. Remember the P&S.
