Yeah, Elan & Nale is much deeper, easy choice.
EDIT: Also, looking at the bracket, I'd suggest using competitions at once, it'll go by quicker that way and also make sure that the ones with less opinions get voted on along with the ones that include popular/unpopular pairings.
EDIT 2.0: While Kudzu and Durkon are just adorable, I think that Haley and Bandana have the getting dialogue thing as an advantage.
