Neville was not so bad dueling as I imagine, nice touch with the Hufelpuf part, I always imagine that Nevill have more trait of them (and that is good becuase to my knowlege they are the more balanced and less propense to go dark).
I supose Harry will need to get Flint another time, its a kind of mini-nemesis, just please dont kill him, its better to see Flint go to jail forever.

To my mind, Neville is a good dueler. He was just caught off-guard by Harry's tactic. Still undecided in Harry/Flint conflict.
