I gotta give a slight edge to Selena. I agree Hayden may be tougher but 5 inches and 18 pounds is a lot to give away. Plus Selena is a performer, have to think she has stanima to perform a 2 hour show so longer the fight goes the better her chances of outlasting Hayden. A neck scissors followed by a facesit and breast smother put Hayden in dreamland.
