Don't really care too much who wins, I'm all about who loses.
I vote for either the girl on the right or in the middle. I imagine them agreeing to team up and take on the left girl in a 2 vs 1 rolling hairpulling catfight. Would be an amazing watch as they take it in turns to maul her.
Both the right and the middle girl have pre-planned everything. They plan to invite the left girl on the trek where nobody will be able to stop them fighting her. They bet to see who will be the first to get her to submit.
They take turns piggyback riding her. While using her gorgeous long blonde hair like reins on a wild horse they're trying to tame.
