The Nissan Path

All,

I've had roof racks before etc. I'm looking more at a cargo carrier/bag. Looks like the family and I will be doing some travels this winter and just looking for your inputs on weather proof bags for the roof? Brand, size, why you like, dislike. Any input will be great.

It seems like the ones I see on the road a lot are either Yakima or Thule. Although on Amazon, the Keeper bags get really good ratings. Another one I've heard good things about is Sherpak.
