Camera Bags

What's your preference? I'm a big fan of KATA bags. Great quality, durable, and if you need them awesome customer service. I have 2 right now. One shoulder/holster that carries my D80 with battery grip and up to my 70-300 attached. I can fit my 50mm and 28-75 in one side Pocket and flash in the other. I also have a KATA 3n1. What a great bag; it functions as a sling for either shoulder or a back pack. In the main compartment I can fit the d80 with 70-200 attached, 3 spare lenses, 2 flashes, a spare body and I can even creatively get my laptop in. In the top compartment, I can fit my bracket, batteries, chargers, etc. I was totally sold on lowpro until I tried these out. There are a lot of great bags out there. Comfort and functionality are key. For me KATA does it. What are your thoughts?
