Hi, I'm going to be in the market for a new set of Ortlieb panniers soon, and currently I'm pondering the choice between the Classic (thick pvc) and Plus (thin coated cordura). I know the "conventional wisdom" is that the Plus is supposed to actually be tougher, but I have read the odd comment here and there that implies the Classic material might actually be more tough in the real world. The Plus is supposed to put up with being rolled up regularly better, but I've read that the Plus doesn't dry as fast, and holds onto mud and dirt more, whereas the Classic is much easier to wash off, and is, well, thicker.
I have had a set of the front & back roller plus since 1998, and did a TransAm with them back then. They seemed fine, of course. A pitbull put a hole in one of my rear ones, which I recently sent back to Ortlieb USA to have professionally fixed. They said the bag was unrepairable, due to the large amount of Seam Grip goop I had put on the thing for the temp repair. But they also said that there turned out to be a number of "pinhole" tears elsewhere on the bag. It just makes me wonder if the thicker Classic material might actually be tougher.
Anybody got any insights there?
