Ortlieb has changed the names of their fabrics and panniers since I bought mine - but what I have looks like what they are now calling the "plus" fabric. And the style of my panniers is the equivalent of the Bike Packer / Sport Packer model.
I know of other folks who have the roller style of panniers, and who have the classic fabric - and they are also very happy with the panniers and with their behavior in wet weather.
I don't think you can go wrong with either fabric.
