Shark, wrong thread.
Why not go for broke, given that it's the last two seasons of the license - bring back Jason Hicks, get Brock Messenger and Andre De Jong in, sign up Te Atawhai Hudson-Wihongi. Then go and get some of their team-mates from the NSWNPL (Bring back Tratty!) to stop the Aussie's whinging.
That would leave 4 visa spots open still, and find players that improve the squad - rather than ones that just provide competition without increasing the ability or collective spirit of the team.
