I have the second gen 22". So long as the bag is under your control--carried on a flight, put in a car trunk--I think there's no problem with the bag's construction. I do not believe this is a good bag for checking given its flimsy construction. I also wish the handle extended another couple of inches farther. I'm five feet, nine inches tall, and I can't imagine trying to pull this bag if I were six feet.
On the other hand, the bag's light weight is truly a joy. Packed fully but not to the gills, I find it easy to lift, and I'm no bodybuilder. This is the only roller I have as I prefer no wheels, but I think I spent my money wisely. It's a good bag for me for golf trips because I can hook this bag to my rolling golf travel bag. Without clubs, I still prefer my Red Oxx XS Aviator.
