any pics of this setup?
I use a ThinkTank airport roll-on bag and a ThinkTank shoulder bag that will slide over the handle on the roller board bag. Both will fit in the overhead compartment and I have carried as many as two NA-EM5 housings and a Nauticam compact housing with domes up to 170mm, four Inon Z-240 strobes, and all camera and lenses as well as my ring-flash and much more. I put trays and strobe arms into checked baggage because they seem to peek the interest of the TSA more than the other stuff does.
