My minimalist m4/3 packing solution

Where I am currently based in Fiji, all my trips involve a flight on an ATR turboprop with a strict 7kg weight limit for carryon bags. I have a great Lowepro roller that holds everything I need, but it's 4.5kg empty and fully loaded it weighs 13 kg. So I have had to get creative. I decided to carry only the valuable and fragile stuff in a backpack, and put arms, clamps, etc into my checked scuba gear bag. So here is what I carry onboard: camera and lens and trigger in housing, macro port and lens, two Inon strobes, a Kraken focus light, my wrist computer, and two sets of batteries for the camera and strobes (not shown).

I found some cheap sort-of insulated lunch bags for school kids that happen to be just the right size. The housing goes by itself in one bag, and everything else goes in the other bag. I wrap the miscellaneous stuff in a layer of bubble wrap to prevent scratches, but sine the bag is never out of sight I am not worried about things getting banged around.

All in, the total weight is just under 6.5kg. There is room in my commuter backpack for a few travel essentials too. Water bottle is 1.5 liters for scale. I am happy to be a m4/3 user!
