Re: Cymbal flight cases
I've got an older cymbal Hardcase that looks like their current model HN9CYM22. I've flown with it in Europe several times and the cymbals have survived well. Just use the soft things between cymbals and tighten them well and you don't need to worry!
The only problem with checking in instruments is that you're never 100% sure if you'll get them in time for the gig :) So a backup plan in the destination country is a good thing to have. You'll need to rent a drumkit/backline anyway so it usually isn't a problem.
