Ok so I have never bought a case before, I have no idea where to start. I know there are cases that just fit "dreadnought acoustics", but I have also heard that "universal cases" sometimes end up doing more damage than good.

So I have a Yamaha FG730S and will be doing a LOT of traveling here soon for a few years (Air Force I landed job entails nonstop travel). So I need something that can take a good bit of rough handling. Any thoughts?
im getting the same guitar this christmas and would also like a recommendation for a good case.
