I bought Storm Case iM2500. This case can be carry on luggage.
I compare this case with Pelican 1510. I like the latch system to open case.
For me, Pelican latch is too hard. I also like soft handle.
Telescoping Handle is more solid than Pelican.
Pelican 1510 has more height than iM2500. Since I put D2x with RRS L Bracket, height was my most concern. Internal view of the case shows how I solved the problem.
