I've got a little too much boyscout in me. I bring as much as I can fit into my bag, but my audience recording bag isn't uncomfortably big. Not 2 of everything, but I'm prepared for most any situation, and have yet to not pull a wav because I didn't have everything I needed. The closest I ever came was to forget my stand, but I had my clamps in my bag and another taper let me clamp on.
When I bring my matrix rig, it is really bad. I bring most everything I have. It's funny that you mention a table! I'm currently working on a backpack to cary my matrix rig that uses parts from an old persons walker as the frame so I can unfold it and use it as a table for my mixer! When I'm at a festi with my matrix rig it is the worst. I even bring a soldiering iron, and I'm starting to put together a homemade 30', 12 chan snake so I can take direct lines off the FOH console. Yea I know... its time to lay off the crack.
