One thing is rock-solid certain about tonight's Super Rugby shootout in Dunedin. It's rare to be as dogmatic about a rugby game but the Highlanders and Hurricanes will sort out their differences in fine conditions on a great surface.
For a century of winters that was a doubtful confluence at Carisbrook as the stadium at the foot of the valley on the other side of the city was open to a cast of meteorological invaders. Forecasts about that impact used to occupy significant commentary and previews in the buildup to games.
Those estimates are redundant with the covered stadium guaranteeing great viewing for spectators and ideal conditions for teams to map out their strategies, so now it's a case of working out who wins.
A week ago my loot was on the Hurricanes to do the business against the Crusaders but poor weather and the hosts' ability to use those conditions and rattle their adventurous rivals dusted that investment.
Double or nothing tonight? Too right, give me the Canes again before a chunk of players swap their Super Rugby kit for an All Black uniform and the three-test series against France.
