Cotty, I use Pelican and Otter cases extensively for sea kayaking. They are waterproof, dropproof and bombproof, but all of mine are relatively small.
I recently customized a rolling airline carry on bag for my outfit. The two primary criteria were (1) it should look nondescript and ordinary in every way (much unlike a rolling Pelican), and (2) it should be sized to fit in both overhead and underseat storage. The most commonly stated carry on size limit is 22"x14"x10" (which is sufficient for the 1510), but a survey of many international airlines for both overhead and underseat size limits established my target maximum external dimensions to be 22"x13"x8" (I'm using inches, as most data I find are from the US). My solution is a common soft side rolling carry on with max. external dimensions of 20"x13"x7.5", and with fairly tough and stiff internal side liners. It will fit into the overhead and underseat bins on virtually any airplane, except for small commuters, where you typically see the bag hand-loaded into the small rear luggage compartment. The inner surfaces are lined with 1/4" dense sheet neoprene (used for shop floor mats) and layers of the same material with custom cut-outs are built up to fit the lenses and bodies. It holds two EOS bodies with grips, 3 L zooms (17 to 200), 4 primes (300/4L IS, 100/2.8 macro, 50/1.4 & 24/2.8), two EF extenders, hoods for all, and a little room for cords & etc. The two heaviest lenses (300/4L IS and 80-200/2.8L) lie flat and are secured with bungie cord, and the rest are secured by the custom fit neoprene and the case itself. Flash & a few other things go in my backpack, and my LowePro bags get stuffed into each other and put in checked luggage. Jim www.jcolwell.ca
