I only own 1 K-wing right now. Bound to order another from a Gen-Con re-seller soon.
I think the model of the K-Wing is absolutely stunning.
I believe the "best" ship in wave 7, in terms of being able to break into the high tier meta, would be either the Kihraxz fighter or Hounds Tooth.
K's and Interdictors will be good support ships for the foreseeable future, but the former 2 will have chances to shine as the backbone of scum lists.
Long live SCUM!
