I concur with Guten Targ... Greenshields would be the go, although I would try and make a play for Hornby.
As for Ah Van ... from what i have seen of him, he has the goods to be a bloody good first grader, I think he looks like a fullback that Cleary is trying to doctor to be a winger. To me an important thing for a fullback is to be decisive on defence, and he showed me that against the Broncos, even hough he was playing on the wing.
