Lighting bags

It's time to amalgamate all the lighting gear to one bag. Excluding tripods/light stands I need a bag that can carry:

4 x Flash guns
2 x Quadra heads
2 x Quadra batteries
1 x Quadra pack (with another being added in the future).
Quadra Adaptor + 21cm reflector/grids/barn doors
Cables and triggers
AA batteries and other accessories.

This is at the minimum, I'm possibly looking at the KATA OC series, Peli 1500 cases and the Think Tank Airport/International, but any other suggestions are welcome. This bag will be used in rough terrain so wheels might not be an option, if you can carry it on a flight so much the better. The main issue I have is how to protect the grids for location work, if someone can suggest an idea for this it would be appreciated.

It's not for carrying camera lenses/cameras, I have a couple o' bag suitable already it's purely for lighting equipment.

Thanks.
