I have front and rear back roller classics and I am very happy. My decision was primarily motivated by price as the classic rollers are considerabley cheaper. I recently picked up the back rollers for $119 at Campmor. I was not aware that the fabric is apparently more durable. One drawback, though not huge, is the lack of outside pockets which forces you to unroll and roll each time you want to get something out. For basic, tough, reasonably priced, waterproof panniers roller classics are the way to go in my opinion.
