I think these forward lines are close to what I'd like. I'm honestly *okay* with JT on the fourth line, as long as he's producing and Fast isn't hurting the third line too bad.
So, with that in mind, for the playoffs I'd like to see:
20-21-36
89-93-61
26-13-19
40-24-10
I think Miller and Grabner like playing with each other a lot and feel comfortable in their reads of one another, based off comments. So I'd keep them together, and Lindberg should be a good enough center for them to make moves.
The only questionable line in this case is the third line, and it really depends on Hayes. I think Vesey-Fast are good at getting to the net, so it's up to Hayes (and whatever D is out there at the time) to create something for them to work with.
The Top 6 is fine. Streiderello just works and the Buch-ZBad-Nash line should be fine.
