If you'll routinely carry more then fits in the trunk, I don't know if I'd recommend it because it's much more awkward to carry and attach and detach when the panniers are in use, but having the panniers available for the occasional extra big load is great. Lately I've been using plain, old satchel, though. So the trunk bag hasn't been getting much use. But I also have a wire Topeak basket that fits on the Topeak rack with the same attachment system, so I just drop my satchel in there. Only issue there is that I don't take the basket in to work with me, so if I don't run my cable through the basket when I lock up, it could wander off. So far, though, no one seems to want to run off with my basket, so all is well.
