I had some similar questions when I was in the market for a ski bag 2 weeks ago. I looked at Dakine but I read some reviews that complain about not having interior straps. Some people also complained that the bag sags and doesn't roll properly on its wheels.
I would've ordered a Douchebag since it seems like they're the highest-rated by everyone. However, they're out of stock and I needed a travel bag ASAP.
Based on an old NS Thread, I ordered a 4FRNT Ski Bag. It's padded and has all the same features of the Dakine Fall Line. It's long enough for 195cm skis (my 190 Deathwish Tours fit great). There are internal straps to cinch down skis and poles, and there's even a padded ski divider to keep bindings from scratching against each other. The wheels are higher quality than the cheapo plastic crap that comes on a lot of roller bags. The build quality, padding, and zippers are high-quality. I'm really happy with it. If you have concerns about the Dakine bag, here's another option
