Beat that horse all you want but the question is relevant. I second the dislike of the OEM panniers and sold mine on.
I'm awaiting delivery of the Bumot side panniers. I received the top box and liked it a lot, in fact, the top box is identical to the Hollan Nomada Pro shown above but with one latch on the rear instead of two on the side. Mount is the same to my eye. Wish I'd known about those as I think the dual latch stuff on the Bumots are overkill.
