Id find a dakine, specially since your flying (?). They make bags, that's what they started doing and they know what they're doing. Plus, their bags have a liftime warranty against normal wear and tear. Don't light the bag on fire, but if anything brakes randomly over time, they'll send you a knew one, or an updated version of what you have if yours was discontinued or updated.
I second packing in clothes thingy, that sounds like a good idea, can't be too careful.
