I'm enthusiastic about these. I've had remarkable service from my current set of Expedition Dry panniers. As I've noted before, the stiffening system on the Expedition Dry is hopeless. I eventually threw out the stiffener and learned to pack the system so it rode well. From the description, it appears this issue had finally been addressed in the new bags.
With a set of these, I'd be able to lighten up the load on the top rack and pack everything a significant distance lower on the frame. Looking forward to seeing them in yellow!
