A bag to fit everything.. Pro Runner x450 AW?

Current gear I want to fit in the bag:
1D Mark IV
7D Gripped
300mm 2.8 IS 1
70-200 2.8 IS 2
15-55 2.8 IS
85 1.8
580 EXII

Will the Pro Runner x450 AW fit the gear listed above with some extra accessories? How snugly? Any room for another lens?

Otherwise, does anyone else have any suggestions? Preferably a roller.
I considered the Pelican 1510 case, but I don't think that would fit everything in.

Thanks!

I have the ProRunner 450AW, according to your gear list, it should all fit...but I wouldn't try to cram any more in there.

Definitely should fit.
I have Pro Runner X450 as well & it can fit the following:

That gear should fit in the 450 AW, but if it doesn't, there's always the Vertex 300 AW. This is mine with everything in my sig except the 120-300 and 10d, and with your lens list, it would more than fit.

I love my x450 - I pretty much fit all of my sig into that bag (minus the 100-400, 5D2, 7D and the bees/PW stuff) for weddings

2 bodies, 35/85 mounted to those... and 4 extra lenses... and 3 flashes... and odd stuff like batteries, polarizer, etc...

Thanks for the help guys! I ended up getting the x450. I was won over by the wheels.

Here is a pic with the gear I mentioned for those who might be having the same question. I could easily find a different place for my strap and fit another lens in if I ever needed too. Same thing with the lens hoods; they would fit in the pockets with their respective lenses which would free up another slot.
