Hard shell vs soft luggage is an eternal debate for frequent travelers. I’ve yet to see anything beyond anecdotal evidence presented for which protects contents better. Seems the airlines or insurance industry might have data to answer it. I imagine the same debate for bike cases will continue unresolved for years.
My anecdote is that I’ve travelled with an orucase more recently, and an s&s couplings hard shell case before that for a decade plus. No damages with either, yet. The S&S hard sure seems it would protect better, especially with the internal braces in place. But so far, so good with Orucase. But sometimes what you think would be better doesn’t turn out to be at scale.
