The Decimator has the first dial to have no reds.
The Decimator not having reds is irrelevant.
Irrelevant to what? It's a first.
Technically, yes
In reality, I have never experienced a turreted ship ever having to K-turn (title-less YT-2400s excepted) so that part of the dial is completely irrelevant until the front arc starts to matter (autothrusters, maybe)
On the Falcon, the K-turn is there in the clutch. I was playing in the final round of a tournament with an elite x-wing list vs double Falcon. It was down to the wire and the Falcon with only a couple points left did a flip to get better position the next turn. It was a risky maneuver, but it worked and he won the game.
It's not something you'll use much, but it's an option if you need it.
