Draggin' belly pan...well, maybe. It really depends on the belly pan. Some pans mount further in like the Macgyver I have on now and it isn't nearly as susceptible to dragging. It's also a bit more robust than some of the other pans.

As far as taking better lines to prevent dragging of hard parts...that's only true to a point. Dragging is inevitably related to speed and corner angle. Also, as someone mentioned earlier, jacking up the rear suspension with preload is necessary for the more aggressive riders. In fact, some of the really aggressive riders install a longer custom-made rear shock clevis to raise it up even further.
