All in all then, apart from looking a little better than the larger, squarer bags, the Corbins are crap? No wonder I've not a single picture of a busa with them on this forum.
I would not say they are crap, but they do not provide nearly as much space as say a set of Givis, or the Trax cases. Also, the other options are a fraction of the cost that the Corbins cost you.
