Anyone got any experience with hard bike cases for transporting? used a soft bag last year to go to europe and got off of the plane with a stuffed rear rim.... I don't want to repeat that experience...

Ideally I'd like a case that could carry 2 bikes (non folding)
Fit within airline max sizes (and perhaps others - eg SNCF)
Be as light as possible (since I'll be flying Asia now and again - 1 piece 25kg max)

Any thoughts?

Cheers
Matt =)
