I'll give it a stab...
Moulson-Hodgson-Stewart
Ennis-Reinhart-Stafford
Foligno-Girgensons-Gionta
That might actually not be too bad, although I could see Reinhart's line facing the same 'lack of space-makers' as last game (maybe flip Girgensons and Ennis?) I'm sure we'll get to see a lot of line combinations before some start to show some chemistry.
Hmm.... Interesting. Especially that Moulson-Hodgson-Stewart line. Possibly swap Ennis and Foligno to give Reinhart some extra body on the wing?
What do you think about this -
Moulson - Girgensons - Stafford
Hodgson - Ennis - Stewart
Foligno - Reinhart - Gionta
I'm not numbering the lines exactly, figuring that between pp/pk duty most of the top 9 are seeing roughly the same ice time, with maybe the best clicking line(s) getting a bit more on a game-by-game basis.
I'm also not thinking much about the whole center vs wing thing as the wings (ie: Stafford and Hodgson) seem to be taking draws and defensive coverage seems more by committee too.
I'm seeing Moulson and Hodgson as the strongest puck-distributors, guys who make the short and mid length passes, see the lanes and open sticks to get a cycle going for sustained pressure. Both can also shoot the damn puck, maybe with an edge to Moulson in tight and an edge to Hodgson for the hash mark rocket?
Then Ennis and Foligno as more perimeter guys who really only "create space" on the outside and mostly with speed and tenaciousness (Ennis) and a bit of brute plugging (Foligno).
Girgs and Stewart each have that combination of brute force, speed, stickhandling and shooting, though I'd give the edge to Girgs for the stickhandling and driving straight for the net while Stewart seems to go more outside.
Stafford seems a mix of the above and Reinhart... dunno? Obviously hopefully a play-maker once he's got some offensive zone confidence. Gionta also dunno, though his numbers the last five seasons (for recent trend) seem to suggest he's more suited to a checking and thirdline scoring role? Small, true, but willing to dig and give it his all.
