I also take a housing & tray for my P&S camera. Since I shoot with fiber optic strobes, I can always use my 'back up' strobe with that combination. I just got back from Fiji and it proved to be a life saver! Also, I purchased a backpack which is as light in weight and strong as I can find. (Laptop, 2 dSLRs, lenses, meds and contacts), then I have a kind of 'old lady' looking rolling carry on into which I put my reg and the backs for my strobes. The thing is - if it LOOKS light, they tend to not hassle you. I have devised a system where I use a locking computer cable setup to 'lock' my housing onto the handle rails in my firm sided duffle and then I pack my strobes, minus the backs (I use Inons) in a rubbermaid container. I have a very lightweight strong duffle, which holds all my dive gear and some clothes...anything which doesn't have to be protected and everything else goes in the firm sided duffle. That worked very well on this last trip.
