I voted for Funa only because I think that Reubs playing on the wing is best for both the team and him. He tries hard at fullback, but he's a winger, plain and simple. Same reason I wouldn't even think about moving the Volvo back there. (
@Mark from Brisbane - that Volvo crack is your fault

)
Funa on the other hand did a decent enough job in the #1 jumper at the back end of last year, although with a fully fit (pardon the pun) Turbo I think Tevita's future is in the centres if he stays with Manly long term. Morgan Harper might be a candidate, but I have grave doubts about his defensive abilities at fullback.
For mine I just really hope Des leaves our wingers where they are and like with Elliot, he brings in someone to play the position who can do the job. So yeah, I hope he goes with Funa.
Of course, another option could be playing Dylan Walker back there with Brad Parker (for the time being) keeping his spot in the centres.
