We have a double DB and a Dakine Fall line, and when it is time to replace the Dakine it will be another DB. The compact storage, no sag and adjustable size were the things that sold us the bag, but the handle placement is the feature that I didn't know we wanted until we used the bag. In addition to handles on the end of the bag, it has two handles on top of the bag which are genius for getting the bag on and off airline scales and baggage carousels and for loading and unloading into the car/ van etc. A thousand times better than the side handle on the Dakine.
As with many others I pack other gear around the skis, but the bag holds things in place really well.
As far as durability goes, it has noticeably less wear from airline baggage handlers that the Dakine at the same age. But, I am a realist. We travel on airlines a lot with skis (and other luggage), it gets worn, it will rub against other luggage and things; and if you are super unlucky it might be the bag that gets caught on something and damaged more seriously. Travelling internationally we have travel insurance and domestically our household insurance covers serious damage should the need arise.
