A definite call for the Leicas, me thinks. I would bring my pair of M6s (one as a spare, obviously) and several of my favorite lenses: my 28mm Summicron ASPH, 35mm Summicron, 50mm Summilux ASPH and my trusty 90mm Summicron ASPH. And I would stuff the works in an F2 Domke, filling all available space with a S#*tload of E100G, E100VS, FP4, Tri-X/HP5 and Delta 3200.
