Even if the warriors don't have an advantage, I can't see how the tigers can.

Both teams travelling from Aus, so I don't think travel will be a factor (not that it's anything like Super 12s anyway). Climate probally won't be a factor, winter days/nights aren't exactly warm in Sydney either. While crowd does have an influence, it is isn't large unless it's an important game for the home team.

I think it'd be best to judge this as a neutral game? Still says tigers +2 at better than even money, just not as convincingly.
