Panniers Commuting, Touring, Laptop
I read the previous thread on laptop pannier recommendations. I notice that Arkel has a laptop commuter bag, which seems ideal. However, it is pricey and not waterproof. Most seem to prefer Ortlieb and since REI carries them and an end of summer 20% coupon might come up, they could be a good deal.
I don't want two sets of panniers, one for touring, one for commuting. I also plan to get groceries for myself on occasion. It seems none of the Ortliebs have a laptop/commuter option, correct? However, does it really make that big of a difference? Also, Ortlieb has a few styles: Backroller Classic, BackPacker Plus, and SportPacker Plus. Either more desirable than the other?
