IMO Wallace, Mullen, Carney, Anasta, Finch are all 5-8's. All bar Anasta have only being playing halfback this year at various times because they had to. We learnt last year that Mullen may be a good player but isn't a rep level half. Don't try and transform a young FG 5-8 into a rep level, it never works. All bar Anasta have had success at halfback (mainly because Braith is a different sort of 5-8), but i still feel they aren't halfbacks.
IMO, the Anzac test halves on form should be Anasta and Prince. Anasta should then sit out of CvC. Finch, Orford & Kimmorley should be steered as far away from as possible.
That would mean in CvC they should pick Mullen, Soward, Pearce, Wallace, Carney all in the mix, and see how they go. Soward & Pearce are the only genuine halfbacks in there though.
LOL@souffs fans thinking Craig Wing would be NSW halfback. Luckily you have that quality NZ halfback Jeremy Smiff. Great player he is!
