I'll probably use something like this: Travelpro Maxlite 21 Inch Exp Hardside Spinner. I travel almost every week and my Travelpro spinner cases are effortless to wheel. If you needed more room, you could get a backpack that will hook right over the handle and just wheel them both along. If you hit some stairs or rough terrain, throw the backpack on your back and carry the other case until you can wheel again.
Here's the backpack I use this way: Samsonite Luggage Xenon 2 Backpack. I can't believe how much I can fit in this bag. Of course these are not designed specifically for music gear, but really hold up well and are much easier than carrying everything by hand all the time.
