Pelicases work. Period.
I bought the 1510 for my Ursa Mini Pro camera and it's peripherals. When I'm flying, the camera fits in well with top and bottom plates removed, including four batteries and a couple of lenses/viewfinder. And when I'm not travelling, it carries my lenses and batteries and the camera itself fits in another bag.
Ergonomically it's very well designed case and easy to handle. It's a bit on the heavy side but that should be regarded as a bonus: it doesn't flip too easily.
I'm going to get a couple more of these in the near future. I really like the form factor.
The only minus I've come across: the wheels make this little annoying sound but not on every surface.
