Bicycle Travel Cases

After Ride the Rockies, I’ve got a couple of centuries around the country this season, and will need to ship my bike on site. After packing my bike in the factory boxes for a few years, I’ve decided it’s time to invest in an honest to gosh travel case. The most common ones seem to be the Tricosports Iron Case , the Tri All Velo Case , and the Thule Round Trip Case.
Does anyone have any experience with any of these? Any favorites? Cautionary tales? I’d like to be able to ship the bike, along with an Allen wrench for assembly, and the roadside tools that I can’t carry on the plane.
