Here is what i use. I can fit an incredible amount of gear into it as well.
I have:
1D
20D w/ Grip
580EX x 2
24-70 2.8
70-200 2.8
50 1.8
85 1.8
Battery Pack for lights
Wireless Slaves
Air Rocket
14" Laptop
Chargers for everything...
I think that is it, but that is just in the main compartment...the pockets on the top and outside of the bag is a whole other list. I keep the 70-200 on the 1D all the time, the 20D goes in its own compartment, along with everything else. The setup looks basically the same as the BH website image with exception of a few pieces of gear being different.
Hopefully that helps, and if you want any more information, let me know
