On what I have seen so far [Latu last year - Madden last weekend] I see more points for the WT coming from Madden than Fainu.
Madden - Play it in their half philosophy - long kicks finding the grass. Managing field position. Be in the best position, more often, to attack. Set up the outside players to stand deeper, run onto the ball at speed. This allows better passing options. More points.
Managing the game to be in the best position to score. Less defending your own line.
Fainu - Faster but still on a learning curve with respect of setting up players around him. Managing team mates to score. Inferior kicking game. More suited to the 5/8 roll.
So, who is best to serve Luai. IMO Madden. Crisper passing, decision making to complement Luai. Take some of the kicking burden from Luai allowing him to plan his attack.
We need to see if Madden can repeat the last weekends effort against a stronger opposition.
Doueihi to get 1st crack at 7. Different skill set.
A Benji headache.
