Yep, I think they look excellent, especially the choice of width for the top. Really want one but already have a Blackburn outpost for my Genesis which does the job ok.
I run a backpack on top of my Porteur rack without issue, so you don't really have to buy a specific rack bag.
It would be for commuting and round town as well, so i'd rather not have to always carry two panniers.
This one you mean? So it can do panniers and/or rack bag?
