Rep eligiblity should just be the same as CricSim eligibility IMO. Let NZ, GB and Vic have teams and play a three-way tourny when Origin is on next season.
That all sounds very dandy in theory but the problem is that there are not enough numbers considering it takes 17 men to create 1 team. I think there might be enough players to have a combined NZ and GB team but that doesn't take into consideration people's positions.
