I voted 6.
To me it's not crap, not great. I'd say good. As JW said, the Tri-Nations has loads of potential and I agree with him on that.
I too hope to see the Tri-Nations become more popular, better and bigger in the future.
I'd like to see the Tri-Nations down here some time too, Telstra Stadium or Suncorp Stadium would be a top place to hold it.
