I would tweak it to this. Heatley and Brodziak have had some chemistry in the past, same with Brodziak and Fontaine. They'd make a decent 4th line. Cooke and Nino look great together, and Haula's got the speed and vision to stay active with them. The 2nd line has big bodies with strong possession skills, playmaking, and goal scoring, and the 1st line is the one we've all come to love.
When you want toughness, keep the top two lines the same and go with a bottom six of:
In any case, I don't think any of us can even purport to know what the lines should actually look like. There is going to be a feeling out period in which all the lines get juggled around, and hopefully it's felt out by playoffs. That's the danger with trade deadline acquisitions: got to find chemistry quickly while fitting them into a role they can succeed in. Doesn't always work.
