Anyone here using hard shell cases like Pelican or Storm to get their stuff around? I've decided it's time to go that route for all-in-one compartment storage for my two bodies, several lenses and assorted do-dads, especially for the ease of access to everything with the opening of a single lid. They've got wheels and extended handles like luggage, which will be handy, and I can keep my Lowepro - Photo Trekker AW II (which has become insufficient to carry all I want to take) on standby for when I'm off on photo-hike adventures. After laying my stuff out and taking some measurements, I'm looking at the Storm Case iM2950 which seems like a good fit for my needs. Wondering what those of you who use(d) hard shell cases have to say about them, pro and con. Your insight is appreciated!
