I picked up a B&R U122 this past week. I noticed there is some poor stitching on the bottom of the bag, where this band of nylon meets its other half. There's also a bunch of dangling threads on the stitching on the bottom, but they don't seem to be loose. Is this nothing to worry about or did I get a dud? Would anyone mind looking at the bottom of their bag to see if this piece of nylon is sewn the same way? Seems the fit and finish should be a little better on a $500+ bag.
