For much of their last Super 15 campaign the Blues used a strikeforce of Jared Payne at centre and Isaia Toeava at fullback.
It was a comfortable fit and a telling combination which went a long way to giving the backline some consistent substance.
This season, the landscape has changed with Payne continuing his career in Ireland and Toeava's schedule likely to be tailored to cope with persistent injury niggles.
Toeava will travel to Melbourne this week with the Blues and start his first trial game against the Rebels, while fellow All Blacks Ali Williams and Piri Weepu are also being lined up for their first hit-out this season alongside other All Blacks Jerome Kaino and Anthony Boric.
"Isaia can play fullback, centre or a few other positions for us," coach Pat Lam said. "At fullback he has the vision and counterattack, he passes well off either hand and he makes those half breaks which get us going.
