Are you trying to make it crash-proof, or waterproof, or what?
I take my camera gear to the field a lot for nature photography, and I have never had to use anything as serious as a Pelican case.
... and then there was the story of the rock climber who was ascending El Capitan in Yosemite National Park. He was about a thousand feet up on the granite cliff when one of the duffle bags fell, and it had an old Pentax 35mm in it. Obviously, it was smashed to bits on the jagged boulder field down below. About a day later, the climber managed to get down there and he found the duffle bag, and he retrieved the Pentax from it. The Pentax case had a slight dent on it, but otherwise it worked perfectly.
