Bag advice!

Hi there,

I am looking for a backpack/bag to carry and I am thinking crumpler. Can anyone recommend one that would suit my needs?

2 bodies - 20D - possibly a higher end/larger body in the future- and a to be purchased Canon film body
24-70
70-200
room for 1-2 more lenses - primes, most likely - 50, 85, 135, 200, etc. nothing telephoto!
light metre
external flash
2 cf cards
15" laptop

Thanks!

Owen
