I'm not partial to that either but to each is own. Also, the DP racks have a reputation of breaking unless beefed up. I do everything on mine from commuting to sport touring. Depending on the ride/season/weather and what I have to carry I use anything from a cargo net on the seat to a set of Cortech sport saddlebags, although you can't use those with the single side can exhaust.
