The Blues are about to face an Australian side for the first time this season and the Brumbies' resurgent scrum, which has reaped two penalty tries in as many weeks, could pose a new set of problems.
Blues forwards coach Mick Byrne has said each of the Sanzar countries have adapted to the new and controversial scrum interpretations in their own ways. His team's set piece was good in the 30-12 victory over the Highlanders at Eden Park at the weekend after it was dealt to by the Bulls, Lions and, to a lesser extent the Cheetahs, over successive weeks, but Byrne's men will enter the unknown at Canberra Stadium tomorrow night.
New Zealand scrums are traditionally more dominant than their Australian counterparts but often fail to press that advantage, while the men from across the Ditch are experts at creating shifting, unstable platforms.
But the Brumbies' strong performances in this area in recent weeks will have caught the Blues' attention. The Australian conference leaders lost 32-24 to the Rebels in Melbourne at the weekend but scored a second-half penalty try, just as they did a week earlier at home against the Stormers.
With a 67 per cent success rate, the Blues still have the worst scrum.
