+1 on Super C with pannier rack. The bag takes loads more weight and 'feels' bigger when its on a rack compared to using the bagman support (I've also broken the bolts on the bagman a few times from carrying too much stuff in it). The seatpost strap attaches the bag nicely to the end of the rack and keeps it pretty solid - I replaced it with a quick release buckle which is a bit easier to get on and off.
