I'd take Agbonlahor, massive amount of EPL experience and I think he would do well in the A-League.
He is the type that'd do well - lots of experience, has never really fired at the top level except for one season, has had a few injuries - bit Ifill-esque, really, though Agbonlahor was more about pace than skill.
By now you'd think he's getting sick of the grind of English football.
