I think you really need to cull a whole heap of awards. There's what, maybe five to ten active fics? When the awards were big, and it was an honor to recieve more than one award - there were like thirty fics being nominated. I remember when there was a choice of 5 trainer fics to win best trainer. Goodness.

And so I think:

1. Cull a lot of awards.
2. I really like the suggestion of best ending. But - I get the feeling it'll be a contest between three fics to see who wins the most awards. You know?
