You have an uneven number of teams.
As for the winner, I'm split between the Danes, the Belgique, and the Estonians. Though if my arm was forced, I'd have to go with the Estonians. Whilst not the 'strongest' or 'sexiest' couple overall, both team-mates have both a high sex-appeal and fitness factor. For other teams, either both are strong but not sexy, or one's strong whilst the other is sexy.
