Thanks for your recommendation--a question--how will it perform in rain? The rain cover in LowePro's keeps me going back.

If you want a sling type bag, I would suggest the Tamrac Velocity 9 or 10. I can carry most of that in your gear list mentioned above. I have no issues with comfort since it has a waist strap to help with support. Changing lenses is pretty easy for me since the bag stays in front of me and the profile isn't as bulky like backpack. YMMV.

I have this one:

You can also attach accessories on the bag depending on what you need(flash pouch,lens pouch,water bottle holder). I have the MX5385 that fits a 580 EX II.
