When the sides played their round-robin match in Canberra this year, the Brumbies rolled out to a 41-23 victory.
They have been changing their style from the kick for territory and start work downtown theories to broader patterns involving all parts of the team.
When the teams met in last year's final, Waikato Stadium was sold out and the Brumbies felt that massive home support helped give the Chiefs the edge. Canberra officials have urged their supporters to create a similar passionate backing for the Brumbies and have challenged them to get more than 20,000 to the ground.
The Chiefs will take the confidence of successive victories against the Hurricanes and Blues where they showed the sort of qualities which mean so much in sudden-death rugby.
After some mid-comp blemishes they tightened their defensive lines and only conceded a try in each game. The lineouts were better than they had been while the work ethic driven by Liam Messam, Brodie Retallick and Tanerau Latimer and the direction delivered by a recharged Aaron Cruden has been huge.
Meanwhile, the Brumbies will use the memories of a campaign which began awkwardly with their only loss at Canberra Stadium, when they were out-thought and outgunned by the Reds, but has since brought seven victories on their home track.
