I think whatever line lapierre ends up centering will take the 1st line defensive match ups. If that's the case, we may see a line like higgins-lapierre-hansen as line 2b or 3 which would be a killer line.
However, this leaves us with burrows, raymond, schroeder, kassian to fill the 4 other top 6 spots. It all really depends on if AV wants to go with a really good first and third line or a well balanced top 9 in which case I'd go with:
Sedin-sedin-kassian (if anyone can carry a rookie it's the twins)
Raymond-schroeder-hansen (two quick defensively responsible forwards sheltering schroeder)
higgins-lapierre-burrows (nightmare to play against)
Volpatti-malhotra-ebbett
