I haven't looked at the stats, so I could be off the mark here, but I think a lot comes down to the defensive capabilities of Bird and Nico which made a difference last week, not necessarily the attack. Nico puts the defenders on either side of him under pressure because he can't hold his own in 1 on 1 tackles against the big men and it's not his fault, it's just physics. Due to this, there are more gaps because other players are trying to cover for him. That lack of confidence causes uncertainty and leads to poor decision making.
Bird didn't have a blinder in attack last week, he just wasn't a liability in defence and our whole defensive unit looked better even though the Warriors forwards started on fire.
I'm not saying this is the sole reason for the win, we obviously went over there with the right attitude, but Nico lining up with Sua (new and still learning) has a whole different feel to it that of Bird and Sua. I know who I'd prefer to be facing the Storm pack who are still pretty huge.
To my uneducated eyes, let Bird keep it simple, defend well, play direct when he has the ball, feed Jimmy the ball early and let Milf chime in at the end of sets and be creative/kick. Bird seems like a a bigger personality than Nico and Milf and is in his element demanding the ball and bossing people around. It doesn't seem to be natural for either Milf or Nico, so let Milf do his thing and over-ride calls when he sees an off the cuff play pop up.
I don't mind Nico on the bench either, i think he offers more that Sims. I know Macca is an 80 minute player, but is it an option for him to cover Moose when he goes off for a short breather and Nico comes on for a burst at dummy half at the end of the half? You then have backs cover in that if push comes to shove, Bird can move to Centre/Wing/FB and Nico can go back to Half.
