I am debating on a six or seven million dollar home and need a little advice. This bag will be used to house my XT w/grip, a 70-200 2.8 or a 100-400 (but not both at the same time) and a 85 f/1.8, and a 580EX flash. It's main purpose in life will be to use at highs school sporting events and as just a general walk around bag when I don't want or need to bring my entire kit. I see a 30D w/grip in the near future, so whatever I get needs to handle a larger body. I am leaning toward the six million as I want something as compact as possible, but I am not sure if it will house everything I need it to? I am open to other suggestions too.

Peace be upon you
