Lightening my Camera Bag for Traveling

Though I no longer take assignment work (unless there's a fat pay check involved...) I'm stoill quite active as a photographer, which will always be my favorite form of mental escape. One thing that has changed over the past few years is that while I own some of the best gear available, I'm increasingly seeking smaller and lighter camera gear. I've managed to create a manageable travel bag consisting of two lightweight cameras with optics that take me from 15mm through 600mm. If anybody is interested I can elaborate on the details.
