We don't have the Roller Plus, but I have the Classic Rollers front and back. My wife has the Paker Plus in back. I really don't like the Plus fabric. After 13 weeks of touring and a moderate amount of commuting to work, the color of her bags have really faded. They are almost pink on the top's surface. I'm not sure if it was the fabric or the color (she has red) It seems like UV affects them more than the Classic material. My panniers with the same exposure, are in good shape, other than the usual scuffs and scrapes.
Satisfied customer here: I have been using a pair of Front Rollers Plus for commuting for a year. The color is fine (mine are red), and has not faded for me (disclaimer: I am in a sun-disadvantaged Northern state). I prefer the look and feel of the Plus fabric. I just ordered a matching pair of Back Rollers Plus for summer travels.
FYI, Back Rollers Classic are on sale this week at REI for $119.
